It's clear why Kristie's tree house is booked solid. It's super clean, well-stocked and will probably be one of the most picturesque and unique places you've ever stayed in. Check-in and check-out was super easy via lockbox. Home does not have wifi (no surprise there), but I was still able to get LTE signal through Verizon. This is definitely a place you'll want to stay for a night or two while on the Big Island.
