My family of four had a wonderful stay at Rene and Bill's place .
Upon arrival we were met by the housekeeper, Lani who helped us get familiarized with the house. Because it was clean and well appointed, we felt instantly at home. It's a tad out of the way so you get peace and quiet yet you really are in a prime place to sample the local attractions.
If there are temporary issues with the house, the owners will let you know right away. For example they promptly told me that oven had issues and they were waiting on the part to repair it. Not a real issue because we didn't come to the Big Island to bake, but it's nice to know there weren't any surprise issues.
This house has air conditioning. I think most houses in the area do not.
The house has a solar water heater so while we had no issues with our small family, there is the chance you could run out of hot water in the evenings. Larger parties may have to conserve the hot water especially on rainy days.
All in all we had an awesome time visiting the Volcano park, snorkeling in the tide pools, exploring the Night Market, downtown Hilo and the Botanical Gardens. At the end of a long, hard day of fun it was nice to come back to Rene and Bill's place.
