We travelled with 5 persons (with 1 toddler) and had booked only a family room. When we arrived, our suitcases got delivered to a little summer house. We got a living room, 2 bedrooms, a kitchen (but no cooking utilities) and 2 bathrooms (2 bathtubs) and a huge terrace. There was another room, but it was locked. We met another big family, but they had bigger kids. They also lived in a house and had 3 bedrooms. So we had plenty of space and were downhill. Therefor we had shortly to walk to the big activity pool.
The activity pool was the attraction for the kids and adults. There was a part of the pool it was 140 cm deep, then there was a 100 cm deeper step (so you could jump from the higher part of the pool 100 cm into the lower part of the pool that was 265 cm deep.
The kids loved the animation, especially the maxies+12 loved Joseph who did a very good job. We were not so happy with the adult animation. We would like to play beachvolleyball daily or even twice a day (at 10 and at 16h), but it was only every 3 days, and animation starts for adults at 11. Most of the time was "low" activity: darts, sjoelen, ping pong. We wanted more action waterball + volleyball.
The breakfast was fine. The dinner was okay it was not very selective. My kids are picky eaters and only didn-t find one day out of 11 nothing that they like. The dinner was also not the kind of meal that swimms in a strange fatty sauce. I ate every evening fish and it was very delicious. For dinner it was sometimes hot in the dining room, but most of the time we sat outside on the terrace and had a wonderful view.
The staff was very nice (most of them were German).
What I liked at the hotel was that it was wide spreaded. You never got the feeling that it was crowded (and we were there in the main season).There were 6 tennis-courts, 3 pools, beachvolleyball pit, Miniature Golf and it has the shady inner court where 2 ping pong tables were and 2 billiard tables. So in the hot noon time you could play nicely ping pong there. There were always people playing with their kids. There was a libary with English and German books and 3 computers. You could bring your own computer and surf the internet also.
At the pool area you could always find a place with an umbrella. It was never overcrowded.
The hotel was too far away from San Antoni. But there was a bus going hourly there and back. There we could do cheap grocery shopping (there was an expensive grocery shop at the hotel) or cloth shopping. There in San Antoni you can meet most of the English tourists whereas in the hotel most people are German. If you like to rent a car book it from home because it is hard to rent a car at a decent price since this year are 3.000 less rental cars on the Baleares.

Myself and my partner (aged 28-36) arrived on the 30th June 2009 and stayed at the Stella Maris for 8 nights, it was quite easy to find as i have been to Ibiza many times. On arrival the reception was clean and what you would expect for a 3 star hotel (spanish rated), the reception staff was nice and seemed to be quite helpful. We was all inclusive so we had to wear wristbands all the time, if you took them off they broke. The room was at the top of a big hill, so you need to be quite fit to lug your case to the top as there is no body to help. The room was spacious and and the decor was a bit outdated but again this is what you expect for 3 star. The view off the balcony was lovely, you could see all San Antonio all the way around to the bay. Not all rooms had such a great view. The hotel in general was clean apart from the toilets near the pool and reception which always smelt terrible and the toliet seats was never wiped clean. The pool near the main bar was nice but very overcrowed, the chill out pool was much better when kids wasnt there but as this is a family hotel there was a lot of kids running around, spashing etc
The restuarant was always clean but got very hot and there wasnt many out door seating.
Breakfast was a little poor, the general cereal, ham and cheese with bread, yoguart and then on the cooked selection...eggs scrambled, eggs boiled, those little crap sausages and.. chicken nuggets???!!! The dinner menu was a little better with some nice fish, meat...but again pizza and chips every day. The evening meal was terrible, not much selection and far to hot in the resturant to eat. The resturant does have a bad fly problem also, so if you dont mind flys on your food and on you whilst your eating then its fine.
The drinks was local beer (half pint plastic cups outside, glass inside) which was quite nice, the wine was local but taste very cheap, the vodka was like water. The bar staff was very ignorant and none of them speak english, i do try to speak a tiny bit of spanish but this didnt help at all. The hotel si a good 20 minute walk from the sunset strip, a taxis is around 7 euros going and about 9 back, you can get the bus for 1.45 euro but this only runs from 8am-1pm, 5pm-9pm.
All in all i thought the hotel was rubbish, we was the only english in the whole hotel the rest was german, all the entertainment was in german (and also was terrible) and so was everything else activity wise.

specifically choose this hotel as it was in beautiful cala gracio, far enough away from san an for relaxing but close enough to restaurants clubs etc (not that san an has any worthy of spending time in!)
on arrival at the hotel we were greeted by a particularly sourfaced ibizian who clearly disliked english speakers, after waiting around for a half an hour we were given a map to our rooms and that was that. The hotel is beautiful and is set on a hillside so it gives views right over the bay but we didnt get to enjoy these... when we arrived at our room they had given us an adjoining room with another couple! we had paid for a double room so to have a connecting door with no lock was unexceptable, the walls were like paper and not worth the 700 pounds we paid!
after explaining this all to another rude member of staff we were told they had no other rooms, but then ten minutes later she produced a key to another room.
new room was dark and basement esque and had a patio which faced a wall...destroyed the whole holiday!i wouldnt stay at this hotel again for these reasons, but more importantly the staff had little or no respect for their customers simply because we speak english!

Hotel Generally:- Rooms in 2 or 3 floor buildings, different styles, set in gardens on a Hill, Nice, clean, In good Repair.

Rooms:- My room was a double (2 single beds, which we pushed together), in a 2 floor circular block of about 12 rooms. Very nice, If I didn't have a real life, I'd be happy to live there! Everything was in good order, and clean. room had a bathroom, TV, Aircon, Fridge, Table and Chairs, outside table and chairs, Radio Alarm clock.

Food:- Quite nice for hotel buffet food. Nothing spicy or out of the ordinary, but I guess they have to cater for a lot of different people, and this is the middle ground. No need to arrive early, as everything was refilled.

Pools:- Clean, not too much Chlorine, no lifeguard, but I don't care about this, as I don't have kids.

Bars:- We were there All Inclusive. Plastic glasses around the pool, glass in the evenings. In the AI program were all soft drinks, Beer (1/2 pints), wine, Sangria, local spirits. The choice on AI was good, and the barmen wern't tight with the measures or funny with you if you drink quickly. Bar prices for those who have to pay looked reasonable, cheaper than the bars in the centre of town.

Disco:- Cheesy, but OK for a late drink, open till 2am.

Cleaning:- Good, nice small touches from the cleaning ladies. I left a laptop, mobile and coins e.t.c. lying around the room most of the week, and nothing went missing.

Shop:- Beach shop is about 20% more expensive than in town, Supermarket is expensive, a lot of things are double the price (or more) compared to a real supermarket.

Sports facilities e.t.c.:- As I'm quite a lazy person, I didn't really use these, but they looked good. I played minigolf, which was OK, although the course could do with a lick of paint. I was quite impressed that almost everything was included in the AI program, Diving or Mountain biking for instance. I think you have to pay for the better tennis courts and the sauna though.

Entertainment program:- Was OK... A lot of it wasn't my cup of tea, but I'm not a family with kids... The evening shows were quite good, daytime activities varied, the entertainment people were good fun. The club song (with special dance - 4 times a day) was quite annoying, But then again I'm not a family / Kid... Entertainment program was in German / English / Spanish (Sometimes they translated into french also).

No-one spoke Czech there, which wasn't a problem for me (native english speaker), was sometimes problematic for the Czech tourists. Maybe it would be useful for them to employ a Czech speaker somewhere on site, as they have 2 Czech Tour operators sending people there.

Other Tourists:- While I was there I would say 60% Germans, 30% Czechs, and the other 10% split French / Dutch / English / Others. It was quite good there wern't many english people... Not so many badly behaved kids, loud people, people complaining about not having a fried breakfast... :)

Surrounding Area:- 2 Nice beaches about 5 mins walk away. A couple of Bars / resteraunts next to the hotel. The town is about 20 mins walk away (quickest way is down to the beach, then along the coastline).

Complaints:- Not a lot really... It would be good if they have a vending machine or something... We arrived at 3am, and thirsty, no water for sale, and tap water isn't drinkable (generally, not just in this hotel).

Same problem after dinner in the evenings... No munchies available to buy... Bar doesn't have snacks / crisps / nuts for sale. No local shops after 5pm. It's OK after the first day, as you know to stock up with snacks from the local shops.

Overall:- Very good, I had a nice holliday there especially for the price (we paid 10,000Kc (£250) each for 6 nights AI, including flights from Prague). Not really much to complain about at all...
