Absolutely wonderful! We highly recommend Liz and Robert's place if you're looking for a cozy spot near Kona. Check-in is super easy, everything is clean and there are a lot of thoughtful touches (phone charging station, boogie boards, snorkels, fins, etc).
Walking distance to the beach and easy access to tons of destinations. Kailua-Kona is a great town. We explored much of the west coast, from Captain Cook up the overlook at Polulu.
