Great spot in the middle of Kailua town. The location is great, just behind the famous Royal Kona hotel and at the end of the Alii Drive tourist strip (you can actually come and go the other way and avoid the sluggish tourist traffic there if you wish, but easily walk to it whenever you want). Very very clean, excellent stock of kitchen gear, towels (bath and beach) and even some beach chairs and umbrella to borrow.
One small heads up: the unit is located above the gate to the underground garage for the building, and there is a fair amount of noise from it. If you're a light sleeper you'll probably need ear plugs, like I did. My daughter however slept through it without issue.
All in all, a great option if you want to be in the middle of the action in Kailua-Kona.
