Charles and Kathy are great! Excellent communication. The Airbnb is a nice, comfortable place to stay and has every amenity you could want. They even lent us headlamps so we could see the lava flow at night, which was an awesome experience.
The location is perfect for exploring the East side of the island - you're within a good driving distance of Volcanoes National Park, Mauna Kea, Mauna Loa, and Hilo. The Airbnb is located in a quiet suburb but within a 5-10 minute drive of shops and restaurants.
