A very unusual kind of accommodation. No walls or windows! You are in the open air all the time. The upstairs bedroom is particularly breezy. Every night there was a tropical downpour; being able to breathe fresh island air while lying in bed was wonderful.
Heather was very welcoming. She brought us mangos, bananas and papayas, as well as fresh eggs. Beds were very comfortable. So was the front (living?) room (again, no walls). Awesome hot water shower a short walk from the house.
Heather's property is ideally located: not more than 5 minutes by car to an awesome snorkeling and swimming spot (Manini beach) on Kealakekua Bay at the bottom of Lower Nāpo'opo'o road, and not more than 10 minutes up the hill to a hiking trail leading down to perhaps the best snorkeling area on the island.
Spending 4 nights outdoors yet not lacking amenities made for a phenomenal stay.
However, if you dislike experiences like camping or sleeping outdoors, or generally like to be shielded from the elements, this may not be for you: expect geckos and waterbugs, the latter particularly active at night, and mosquitos (although the bedrooms are protected by nets).
