Kristie made sure we had EVERYTHING we needed to know about the tree house well ahead of time - videos, details about the house, her contact information - and it was even better than described. It was the best place we stayed on our trip for charm, privacy, functionality and uniqueness. The tree house is such a fantastic place to stay, we would do it again in a minute.
The road to get in is paved, but definately rough. We had no problems with our little sedan. There is a counter/sink area (cute) with paper plates and a good knife provided, but since there's not means to do any real cooking, plan your food ahead. It's also a trip to get groceries, so load up in Hilo. Did you notice it has a trap door, hanging bed, wonderful mattress and a pully for raising up your baggage? So worth it.
