Who this place is for: adventurous traveler or couple looking for somewhere unique, off-the-beaten-path, and who are willing to try something different. Think "glamping" in the jungle.
Who this place is not for: those who don't like jungles.
That being said, we absolutely loved our stay. The property gave us a needed break away from the busyness of modern life. The property and buildings are beautiful. Even though it's off-the-grid and eco-friendly, there were a lot of nice touches and conveniences. Even the outhouse was nicely designed and comfortable. I do say "glamping" because there are some aspects that are more camping than a traditional stay, such as cooking on the charcoal grill on the lanai, showering outside (awesome, btw), and the noises of the jungle at night. There are also mosquitos (as there are everywhere in Hawaii), but nothing the provided bug coils and bug spray couldn't deal with.
Overall, we loved our stay and totally recommend this place to those who have the time to enjoy this part of the Big Island.
