Vaulted ceiling. Open air design. Very relaxed feel with great views and cooling breeze There is AC if needed at night.. I can usually take or leave having a pool, but this one is special. Just the right temperature, no chemical smell, and rounded edges everywhere. Every day we watched the crashing waves while relaxing in the pool. On site management was also very friendly and helpful. Will definitely try to return to this unit again. The owner, David, was prompt in answering any and all questions prior to our booking.
