If you’re staying in Volcano, I don’t think there is a more interesting option than the treehouse. We visited the area for two days to celebrate my Wife’s birthday. The layout and decor are great, and the uniqueness alone can definitely warrant the bill. The fees associated with this place is rather high for Airbnbs and it wasn’t the most clean I’ve stayed in (mattress cover stained, hair was in the shower drain upon arrival). I believe the popularity of this place most likely plays a role there. Overall, I would recommend it though!
It was an experience we won’t forget!
