This is such a serene place. My partner and I stayed here in the middle of a two-week trip to the island, and it was wonderful to stay at such a remote location for a few days. You really feel like you're in the middle of a jungle. It was incredibly quiet, aside from normal nature noises (birds, etc) and the occasional peaceful sound of rainfall against the metal roof. What a wonderful place for reading, writing, and general relaxation and contemplation.
Everything was very clean upon arrival, and response times were super quick. The house was very well laid out and made great use of the small space. The WiFi was slow and a bit flaky, but that is to be expected—bring a book! The temperature stayed surprisingly consistent inside the house, even though the night-time lows are significantly colder here than elsewhere on the island. The bed was comfortable.
It's worth noting that the kitchen is minimally stocked and the nearest grocery store is a decent trek away, so if you're looking to cook during your stay, buy everything you need on the way there. (If you happen to be there on a Wednesday, I highly recommend the Farm to Car market about 20 minutes away.) Also, remember that this place is in the middle of a jungle—expect some small "visitors"!
We very much enjoyed our time here, and would highly recommend it to anyone looking to disconnect as part of their trip to the Big Island.
