Phenomenal!
The Treehouse is a wonderful space. Clean, comfortable and well-appointed, of course, but also a lovely retreat amidst the fern trees. From drifting off to the enchanting sound of Coqui frogs (they stop around 11pm if that troubles you) to waking to sunrise through tropical foliage everything about our stay was magical.
Greg was incredibly accommodating even though we arrived far later than anticipated. His directions and check in details were perfect. The only thing we had to do was empty the de-humidifier morning and evening—which took only a moment. We stayed our first two nights on the island and it was a great introduction to Hawaiian hospitality. Would absolutely stay again and recommend to anyone who want to stay off the beaten path but still have all the comforts.
