Great house, great location!
About no air conditioning - we were a little hot the first night, but once we opened all windows and screen doors, it stayed quite pleasant. The week we stayed was quite warm (mid- to upper-80s), and the house was generally warmer in the afternoon, when we were typically out and about, anyway. The fans kept everything moving... and if we got warm, we just sat outside for awhile and enjoyed the breeze. You're on a tropical island...enjoy the experiemce!
Would definitely recommend!
