A/C ineffective. There is a portable A/C unit in the room but it stayed between 88 and 92 degrees from 12 noon to 8 p.m. You can open the windows but the lowest the temp went down to was 88 during the day with windows open. After 10 p.m. at night till 10 a.m. in the morning you did not need the A/C and it is comfortable. Of course if you are out all day as you probably should be (I usually do my business in the early morning and come home for an afternoon nap) this won't be a problem. You could use a car to get to town and to the airport. There is a wonderful view from the balcony for those Kona sunsets. Shannon is a very congenial person. It is good value for the price, the place is immaculate and cozy.
