Beautiful, classy home in a beautiful location. Very comfortable for 2 couples with a great, updated kitchen for preparing meals. The last hundred yard of the road is rough cobbles so drive slow. But you don't need to worry about traffic noise - there isn't any traffic! Great landscape to explore for plants and birds.
Very short drive to Volcanoes National Park where Kilauea was putting on a great show with a lava fountain and lake in the caldera. Nice, paved hike out on the south side for best views. Good footing so you can check it out at night as well.
We also signed up with the Friends of Hawai'i Volcanoes National Park to take a 6 hour tour with one of their guides. It was fantastic. We asked for a geology expert and got a retired professor of geology to give us a 6 hour seminar as we went down the Chain of Craters Road.
Take Naomi's advice about bringing potable water seriously. Among 4 of us we went through about a gallon a day. The general store on the military R&R camp (open to the public) inside Volcanoes National Park was the most economical place to pick up extra water.
I wouldn't hesitate to stay here again.
