As mentioned, the individual rooms are located in small villas. We were told that we were staying in a Premium Beachfront Room, which would be an upgrade by one category. Main difference to the Deluxe Beachfront Rooms seems to me to be that they are closer to the main house. Supposedly they are also quite slightly larger, but I can't see any difference in photos.
First a view of the house, next to it are paths to the beach.
