This studio is big and bright and very comfortable for two, and appears to be recently renovated with a very large double-sink bathroom. Steve, our host, is very nice; on our first day he greeted us with fresh papaya and star fruit from his own garden.
If you plan on doing any diving, the Harbor where the dive boats leave from is only about a 10min drive, very convenient. Most of the beautiful beaches are north of Kona, so this is a good spot for exploring that part of the island; however, the best snorkeling spots (Captain Cook and Two Step) are south of Kona, both about a 40-45 min drive from the studio. Note, that the studio is in a residential area, with no shops or restaurants within 5 miles; the nicer restaurants are in Kona, about a 15-20 minute drive south. The kitchenette is very basic and does not really encourage cooking at home, so Kona is your best bet.
The only negative is that a rooster woke us up very early in the morning, so we had to sleep with all windows closed.
