Thalassa is a nice hotel, well situated in front of the sea. The rooms are rather small but quite OK. Some are facing the sea which must be wonderful (unfortunately, we were in the back).
Service was friendly and helpful. in the back there is a big parking lot were you can leave the car at a very reasonable price of 4 €/night. Breakfast is very extended and gives a good choice.
The hotel has also a quality restaurant at reasonable prices and with a friendly service.
All in all a good stay at the hotel at a rather high price for the rooms, taking into account that they are good but small. On the other hand, a nice place for visiting Camaret-sur-mer and the region.
