My husband and I spent three days in the Lava Sanctuary, main house, loft and it was a really special experience. Jade lives off the grid, but provides a very comfortable living space with a comfortable king sized bed. She was a really gracious and generous host, and actually wasn't even present for most of our stay. Her house keeper, Lindsay, was also very friendly, but not overbearing; she took her interaction cues from us.
Because it is off the grid, it wasn't luxurious; parts of the house are open to the air and there are a lot of small fruit flies and a few mosquitoes. However the bed has a mosquito net, and the fruit flies are only annoying if you really hate bugs. You have to be careful of electricity use at night, but that's easy as there isn't much need for electricity other than a light or two, and all that's required is that you turn off the ones you aren't using.
The house is literally on the lava fields, which was awesome and beautiful. It's also a short drive to Uncle Robert's Club, which is a community of people who support the Kingdom of Hawaii and a treaty with the U.S. (Interesting people to talk to!). There is a bar and a few places to get food, and it's near a rocky beach where we saw a surfer go into what appeared to be a very dangerous situation and make it look easy. Unfortunately, we didn't get to see any live lava, because it was too far in to hike to.
I'd highly recommend staying with Jade if you don't mind a more simple living situation. You need a car, and it's about 15 -20 minutes drive to the town of Pahoa, and its restaurants and supermarkets. However, the uniqueness of the location makes out 100% worth it.
