I’ve always said that the temperature in Hawaii is the temperature that human beings are meant to exist at! Well, that’s not true on the big island, specifically Kona and at this condo in July. The heat inside this unit was unbearable for us. So bad, that we left a night early. Yes, the host was up front in the listing that there’s no AC. I really should have paid more attention to that, especially because my hubby has a medical condition and is extra sensitive to heat. But I don’t (have medical reasons) and I was totally miserable! Watching a movie in the family room at night would have been awful. It really doesn’t cool down at all but in afternoons/evenings it was really bad with no winds. Out of curiosity, I went back and looked at other units that I had compared against this one and those did have AC so I was kicking myself! Thankfully Noel (the property manger) brought us her portable AC unit for our bedroom so we could sleep at night and watch movies on our iPad. We were so thankful for that!! Otherwise, we just would have left after the first night. As it was, we lost a night and left a night early to move onto our hotel. I’m sure, outside summertime, it’s glorious. The condo itself was clean, spacious and had everything you need. If the heat bothers you at all, I would think twice about booking during the summer!
