We were only there for one day.
It's a great location, nice neighborhood and nice house. The price was reasonable for the Kailua-Kona area. The place was comfortable and our host, JC, was pleasant and helpful. Other communications were all good.
Our only problem was the bathroom and bedroom were not as clean as they could be. (I suggested they hire a new cleaner.) The kitchen and living room were perfectly clean.
All in all, a nice place, nice people, and a good value.
