We spent four nights in the Little Yellow House on Hawaii and had a great time. It is out of the way and very peaceful, but really not that far from Kailua-Kona if you have a car. If you want to go carless, this really isn't the place for you.
The Little Yellow House is richly appointed with thoughtful touches, including paintings by your hostess. It is a small space but it isn't lacking.
The biggest downside is the kitchen. If you need a four burner stove and full size refrigerator, look elsewhere. But there is a BBQ just outside and enough of a refrigerator that you can keep drinks, leftovers, and tonight's meal ready.
