I have been to this hotel five times,the time before my recent visit was with my family 5 years ago.
This hotel used to be a big family hotel, now it seems to be full of young people there just because it has turned into an all- inclusive hotel and its not too far away from San-antonio.
The pros- Its very clean, around the hotel and in the rooms, the rooms are a fair size, the staff are friendly and its in a lovely area not too close to the noise of san-antonio but close enough for a good night out (about 5 min water taxi ride.)
The Cons-Dont expect too sleep much if your in the hotel, the walls are paper thin, the guy next door snored so loud every night and all day! The food was cold and boring.
I have stayed at the bergantin all inclusive which is just up the road and it is much better!

we have just returned from two weeks of hell. payed for all inclusive and ate out most of time. the food was awfull. no entertainment at all , pool area was never cleaned, they ran out of vodka and were giving us all martini complained and was told to drink what i was given , please do not go there if you are a group of young boys. they treat them like crap even going into their rooms and pulling them out of bed for snoring. tony and bepe the bar men are slezy. they hit on anything and just keep on and on. its absolutly disgusting. iam 50 and they just never let up, even after being told where to go they drool after the young girls,please do not go there

Hotel is very close to the beach and sea.
Water ferries excellant value for money.
Bars and diners close by.
Staff very helpful.
Rooms were very basic.
Website stated pool side bar and live entertainment, pool side bar was not open and there was no live entertainment.

Me and my sister stayed in a normal room (not apartment) in Hotel Rivieria and couldn’t fault a thing! The staff were all really friendly and reception was staffed 24 hrs. The hotel had loads, two big pools and had lots of sun loungers. There’s a bar, lounge area, pool tables, games and computers with internet access. The room was perfect, extremely clean, nice bathroom, big enough with plenty of mirrors for getting ready  The room had a safe, it’s 3 euros a day with a 5 euro deposit. I definitely agree with the review below, the air conditioning is worth it and only 10 euro deposit. The room was cleaned every day and loads of fresh towels provided. Have to say, the hotel was really clean – I’ve stayed in a few hotels in the same price/ rating range and this hotel was far above any other I’ve stayed in. There were families, couples, small groups and larger groups and it had a good atmosphere, nobody was really rowdy. I would probably agree with the review below about families with young kids, it might be a bit loud at night although I’m not sure you’ll fine a hotel in San Antonio/ San Antonio Bay that isn’t a bit noisy. Compared to other hotels in San Antonio that I’ve stayed in, this was quite.
The hotel is in a good area, loads of bars and restaurants outside the hotel and the beach is less than two minutes away. The main part of San Antonio with the west end is quite a way though, about 15 - 20 minutes walk. You can walk from the beach just outside the hotel along about 5 different little beaches, all the way to the main part of San Antonio so there are loads of beaches to choose from. You can also walk along the road which is almost parallel to the beach, through a few clusters of bars and restaurants. I wouldn’t suggest walking this to small groups of girls in the night before/ after night out, although there are bars along the way there are areas that are a bit disserted. There’s also a ferry boat only 3 euros. Getting to San Antonio in the night can be a bit of a nightmare, you pretty much have to flag down a taxi as the hotel won’t ring one after 6pm (absolutely the only negative about the hotel, if there had to be one) – just be patient and on the strip outside the hotel and you will get one. Tip – don’t try walking up to the bus stop at night either – you have to walk up an even more disserted road and the bus stop is on a busy road with pretty much nothing on it.
So, great for the day time bit of a trek for the night (although all depends on where you’re going out) but if I go to Ibiza again I would definitely stay there 
