Riviera Hotel is a 2 stars hotel maximum. We are convinced that all the positive reviews are not written by tourists that visited this pitiful hotel.
We have not noticed a single thing to save the hotel a bad image. Everything was a disaster.
Rooms: small, ugly, the sheets and the towels were not changed at all during a 7 day stay; the bath does not have a sewerage system, a moldy smell that we could not get rid of all the vacation.
The promised fridge is a sweet dream. The receptionist wseemed surprised by our inquiry regarding this matter.
The TV is available only after paying a guarantee deposit of €20. You are not even informed about this by the receptionist. I entered the room and was disgusted by its appearance, opened the windows as quickly as possible because the smell is too heavy and then after to console myself about the condition of the room, I lay down and tried to switch on the TV. Surprise! No remote control! This is the confidence that they have in their own clients: they require a deposit for the remote control!
The area is noisy anyway, but the disturbing part is that the hotels walls are so thin that we hear everything on the entire floor. We were unfortunate to have some noisy teenagers as neighbors and at 3 o'clock we tried to call the reception to calm down the spirits a little bit. The room phone was not dialing any number! We asked afterwards, internal free calls are not possible. Never saw something similar even in a 2 star hotel. In the room, there is no instruction for using the phone. You must ask the receptionist how the things are working.
Food: a nightmare. What else can I say? We did not have a decent meal in this hotel in 7 days. Beside the fact that is not diversified, the food is looking graceless and disgusting, not well cooked and tasteless. There is an automatic machine for beverages - all are artificially made and very sweet. The coffee is not an option as it has a strange taste - better not even try it.
Even their own traditional food is awful. They seem in desperate need of a chef. The staff are OK, they are trying the best but they seem to be short in number. I had the surprise of being served by the receptionist lady!
Even more disturbing is the fact that you must stay in line 10-20 minutes with a ticket in your hand (I felt I was in a school canteen). The shocking part is that you pay for this as if you were in a 3 star hotel!
Above all, you are not allowed to take your food on the terrace (not even the a coffee) and inhale at least the fresh air. In the basement the heavy smell of the disgusting food is not allowing you stay more then 25 minutes, it was practically suffocating me.
Reception, staff: acceptable. They are trying their best, the problem is that the hotel is not a 3 star and their efforts can not make up for this very fact.

The bottom line is that I am strongly not recommending this hotel, it does not deserve the money. I do not know how it got 3 stars. It's a pity, especially for foreigners because it leaves them with a shadow image of beautiful Spain. Our vacation was somehow saved by the visiting tour we made in Barcelona and a one day cruise along Costa Brava coast. The nicest site is Tossa del Mar. Go there directly, but if you choose Santa Susana/Costa Miresme avoid Hotel Riviera. It's your vacation, is your money and you deserve more.
