The Hotel Riviera is one of 5 hotels all under the Lifeclass brand, which have access to the same central health & wellness facilities.
The whole experience was very expensive and extremely disappointing and I would not recommend staying at this hotel. Firstly the hotel is dated and tired and looks in need of a refurbishment. This extends to the health & wellness facilities which photograph well for the website but are pretty aged and uninviting in reality. Also, despite a high room rate, only access to the main pools is included - for example you have to pay extra to use the sauna.
Secondly the service was very poor. Calling either reception or the spa complex to make a booking for a treatment normally took numerous attempts before anyone answered, and when they did, the tone could best be described as curt.
Thirdly, we stayed on a friday night and there was a bar on the beach front opposite the hotel that played extremely loud music until 1am. Our room was as far away from the bar as possible so I would have thought that anyone with a sea facing room would have had a similar or worse experience. Reception proved little help when they did answer the phone, first claiming that the music would finish at 11, then 11:30, then 12 etc. This was of course when they answered the phone. When we complained in the morning we were not offered any sort of complementary service and indeed were told that's what we should expect having a beach front room.
Overall, a very poor hotel.
