Hotel Venezia does not exist anymore (there is now a big supermarket on the same spot). Hotel Roxy is somewhat rundown but ok. On check-out we were quoted a much higher price (16000) for the double room than at check-in (12000). Otherwise, there are only two or three more expensive hotels in town.
The Thermas de Socos mentioned in some guidebooks do have a camp site with pool (closed outside the summer holidays), but generally it is purely a mineral water treatment spa: bathtubs rather than Jacuzzis.
