Quaint and clean, nice location to be near downtown Kona. Great value. We liked the large bathroom and just needed a place to sleep, so the room was great. Plenty of shopping in walking distance. Marc is a super-super-duper host! He helped us out with our specific needs.
Be aware that Ubers and taxis are hard to come by on this island at this time. You may be better off renting a car. Depending on the times you need to travel around. Leaving the airport midday we found an uber easily, but not early early in the morning.
We toured Mauna Kea and recommend it! Lots to do on this island, and Marc's place is a great deal!
