the room had a good layout. i liked that the rooms looked beautiful. i found the setting to be beautiful, though it's a bit out of the way.

The restaurant was difficult for celiacs like me. i was brought meals with gluten in them, after asking three times if they were gluten-free. drinks were very expensive. Five euros for a bottle of water.

The gym at this hotel was great. It really met my expectations with its wide selection of weights available.

i was disappointed with the evening food options, especially since i paid for half board. the menu felt very limited, and some of the nicer dishes required an extra charge. one night, i ordered room service for a change, i then found out this also incurred an extra cost, even though i was on half board.

the hotel had a beautiful beach with fine views. it was difficult to leave the comfortable sun beds. the main bar cocktails were delicious. it was a perfect lounging spot after the beach.

i was surprised that half board did not include water. the options were limited and sometimes lacked sides. drinks were expensive. a basic non alcoholic cocktail cost 15 euros.

The staff was kind and helpful, providing really good service. The hotel's design was beautiful and contemporary. Rooms had spacious terraces. The DJ played amazing music by the pool and bar throughout the day. I particularly enjoyed the music selections.

Waiting times for lunch snacks at the beach were sometimes long. I experienced waits of 45-60 minutes even during the pre-season.
