Solid, but with some hiccups that could be fixed with relatively minimal effort. The apartment was very clean, and it is fairly well located along the coastal road in Kona. The building is a bit of a dated concrete hulk, but the unit itself is up to date and comfortable.
Some gaps in the setup - e.g. coffee maker but no coffee, Keurig machine but no capsules, etc. And communication with host not ideal - we arrived to a notice on the door that the unit would be fumigated in the middle of our stay and the host first responded by telling us there was nothing she could do about it. After pushing, she agreed to reschedule. Oddly inhospitable reaction to a fairly basic and obvious guest expectation, though also of a piece with much of the service experience as a visitor in Kona. The town, in general, seems uninterested in having visitors or customers at all, even when the entire business (as with this Airbnb) depends on precisely that.
