the beach volleyball was fine, i guess.
The room seemed outdated, and the tv barely worked. the bathrooms were especially small. They was like relics from another decade! also, a waiter at the pool would have been nice given the expense. Getting my own drinks felt a bit much

Acceptable Stay with a Few Drawbacks

helpful staff watersports activities fishing dock old room uncomfortable furniture seaweed problem
Gabriel at the front desk was helpful. He remembered me when I passed through reception. I loved the watersports. Fishing from the dock was a plus.
The rooms are old. Furniture and beds were not comfortable. There were basic TV channels and no Netflix. The beach area was small. It was covered in seaweed. The seaweed made it stink.
