The description was accurate and the home was welcoming. We had no difficulty finding the house at all and used it as a base station for our exploration of the island. Guy was present frequently with helpful tips and suggestions for places to see though we usually wanted to follow our own plans. It was 'winter' so mosquitos weren't an issue and our kids had fun with the geckos that roamed freely.
The view from the Lanai was fantastic and we loved watching for whales while sipping coffee in the morning. We felt very welcome in the home.
As for the location it's important to know that it's on the Kona side of the island and not the Hilo side. It's in a subdivision about 1/4 mile away from the ocean up the side of the island. Stop at the grocery store before you get there because it's a long ways away (12 miles or more).
We had no issues with the cistern water (there was plenty of hot water for showers and baths for five people for five days) and Guy supplied us with plenty of drinking water.
