My wife and I recently went on our honeymoon at this location. The treehouse is absolutely beautiful, and because it's very private it was a great place to get away! We had an absolutely wonderful time here!
Things we enjoyed:
1) The treehouse is gorgeous. The setting is very private, romantic, and very natural. The bamboo of the treehouse, as well as our close proximity to the rainforest, made it the perfect place to get away from the city.
2) The owners were very friendly and responsive any time we needed anything.
3) When we wanted to stay inside, having the smart TV available was a wonderful way to relax together.
4) One thing we thought was really cool (and very useful) was the pulley system, which was a great way for us to get our luggage from the ground up into the treehouse.
5) The bathroom (and the shower specifically) were very spacious and beautiful.
6) Lots seating outdoors on the porch.
Things we wished were better:
1) As with many places like this in Hawaii, there was no AC or fan in the unit (although there is heating). When we first arrived, the windows and doors were all shut so it was very hot inside. It did cool down after a couple hours with the windows open, but it did still occasionally feel a bit hot inside.
2) The water for the unit is supplied by a water tank which is filled by the rain. I think there wouldn't be any trouble if we had visited during a rainier time, but during our stay, it rained very little. This meant that when we took showers, the water ran out very quickly (less than 10 minutes of shower time). Even though it didn't rain, the water did recharge after 5-10 minutes or so, but it was a bit frustrating when the water suddenly stopped mid-shower.
