I would honestly give this place 6 stars out of 5 if I could. In every sense, this place is amazing. Naoko and her husband are the best hosts ever. I was floored by their hospitality and the cleanliness of the place. The space is large and can comfortably fit a large group. It just a 10 min drive to Kailua-Kona downtown and all the beaches. The place is modern with a touch of Hawaiian homeliness. The place doesn't show up on google maps due to no fault of the hosts but the place is worth the effort of finding it. The entrance is right on the freeway right before Ahikawa street if you're coming from Kona and not on Ahikawa street.
Whenever I go to Big Island in the future I'll always stay at this place for sure. :)
