This is a great place to explore the Kona area (or all the west coast!) a bit away from the noise.
Best things: the place was clean, nicely furnished, lots of facilities, etc. Very comfortable. Being in the first floor was convenient to access the pool (a short walk on a concrete path) but people need to know that access to the main door is through a staircase (with no ramps). Not a problem for us but could be for other people. It is not in the main Kona area (which was great for us as we wanted to stay away from the most busy places). The couple running the apartment complex (Jimmy and Yuki? hope I got their names right!) are extremely friendly and gave us a lot of helpful advice, like the public access to the beach near the Sheraton to swim in the Keahou Bay (if you don't mind jumping from a concrete step and getting out over some easy to walk on rocks). Even if you don't intend to swim the view is great.
The host was excellent, with tons of information as soon as we booked and answering the few quires we had after arrival very quickly. Getting there from the airport and checking in was like clockwork, everything worked seamlessly. They also allowed us to stay a couple of hours past the checkout time (but we were lucky the next person was not arriving that day!).
Highly recommended!
