loved the orvay apartments, first of all the actual inside was clean and tidy - the staff were always friendly and helpful.
group of four girls and we went 5th july 11 for a week. the room we stayed in was for four people it was nice and big and accomodated us even though we didnt spend alot of time in it. The air con worked really well, as it was so hot in the corridoors and outside we would walk into a nice cold room.
Theres plently of places to eat, theres resteraunts in the square the hotels in and at the actual hotel - all nice food. but i would reccomend the curry club. The small supermarket sells more booze than it does food..bonus! and its cheap, the food is fairlypriced too!
its walking distance to the main nightlife - westend and sunset strip. At the west end people are constantly offering you deals for booze, and they are good offers. we didnt really go to the big clubs as its not our scene. Your very close to ibizas main beach which was ok as a beach been to better, we tried to find the other beach people had spoke about but couldnt think of the name. the pool is on the roof and is small but does the job and its clean.
we each spent about 350-400 for the week and we went out drinking/to the bars/beach/eating everyday. although loads of people said they spent nearly twice this but because they went to the big clubs.
San antonio is really busy, but orvay is situated in a great place were your away from the noise but still 5 mins away from all the action.

In the old part of San An Town and only a 5 min walk to the 'West End' and 10 mins to Eden night club.

Its a lively hotel with mainly young clubbers and hen and stag's staying here. The food is really nice....I pretty much went here most days for food. Chicken Curry on a friday is a treat :-). There is a pool table by reception

The rooms are pretty basic, but your in Ibiza to party not to sleep so they do the job. Some rooms are pretty big, depending on how many people are in the room.

The pool area is alway quite, its on the roof and usually alway a sunbed.

Supermarket is just down the road 1 min walk and sunset strip is only a 5 min walk.

I stayed here with 5 friends from the 6th-13th September. We stayed in a 2 bedroom apartment which was perfect. The rooms were a decent size, one of which had a balcony, and the living area was big enough for the 2 beds, a table and chairs, and a storage unit. There was also a seperate kitchen with fridge/freezer, microwave, and plenty plates, glasses, cups and cutlery. The living area also had a balcony.
The air-con in the apartment. was excellent There was a unit in the living area and both bedrooms, and on the first night I had to turn it up during the night as it was so cold. We were charged only 6 euros a night for this.
We loved the roof-top pool. As people have said, it isnt huge, but it doesnt need to be. Because the area of the roof is quite small, we chatted to everyone up there and it was a really friendly atmosphere. We were able to take drink up as there is no bar, and you can see the sea from there too.
We ate in the hotels cafe everyday for breakfast, a couple of lunches and 1 dinner, and was never disappointed. Prices were really reasonable.  They had sky in the cafe and would always put a channel on when we asked. They also had decent wi-fi, and you could get the code from the barstaff. The staff in the hotel were really friendly. We had a run in with the manageress on the 3rd day, but to be fair, we were drinking out of glass bottles in the pool. She did apologise later in the week tho for shouting. The staff were also happy to call you a cab which turned up within 2-3 minutes.
The rooms were clean, and the maids stopped by every day, but we never really used them except to change our towels.
Location is decent. Right next door to the Ibiza rocks hotel, and once you have your bearings, both the sunset strip and west end are less than 10 minutes walk away. There is a small supermarket just round the corner which sells everything you would need, and the prices are decent enough.
I have stayed in about 10 different hotels in San Antonio, and this is the one I would look to return to the most. We paid £75 for 7 nights, which to me is an absolute bargain!
 
If you are staying here during the high season, I would thoroughly recommend doing the Ibiza rocks the boat trip. 35 euros, out at sea for 3 hours, 2 free glasses of sangria, great selection of music, and a set from an acoustic guitarist, playing the likes of Oasis & the killers.

I stayed here with 3 of my friends we had a room that slept four which was a bedroom with two beds and then a couchbed and camp bed in the living room. all very comfortable and clean. excellent location-walking distance (5-15mins depending on your route) to the shops and 'west end' great taxi service from reception, bar which serves food downstairs didnt actually eat there but ate breakfast in one of the resteraunts in the little square its situated in and was fab. staff where friendly rates where cheap we went self catering and had a great kitchenette-decent sized fridge-large bathroom and a nice sized balcany. the pool on the roof is small and thers nomore than 2 dozen sunbeds so get up early if you want one! but its great for what it is! we had 4 nights in here the aircon is really cheap and the safe is too. id highley recommend this place to groups of friends going for a real party weekend in ibiza who just want a good location and a clean palce to get their head down! if and when i return to ibiza ill certainly be staying here again!
