We loved our stay and the house and backyard was beautiful just like in Charles' amazing photos. Charles & Kathy were very responsive and flexible to our arrival/departure times. They even brought us papaya and bananas that they grew! It was so relaxing and quiet being outside the city.
Tips: It's good to plan ahead for food or activities because Hilo and Keaau are about 20 min away. T-Mobile had no reception in the area so if you are driving with Google Maps on your phone, it would help to have a phone with another carrier like AT&T. They have wifi in the house though!
