The Hobbit House is beautiful and minimalist. I spent a good deal of time laying in bed, just admiring its actual structure. It is minimal in that there isn't a ton of furniture, kitchen amenities, air conditioning, etc. but we were totally prepared for that, and were never uncomfortable or lacking in necessities. You're not really roughing it if you can take a hot shower! The one thing I wasn't prepared for, despite the description and other reviews, were the jungle sounds. I had no idea tree frogs could be so loud, or that parrots could sound so... angry. Sleeping in the loft vs. the main floor made a huge difference in this regard.
Some highlights: we could see the glow of Kilauea from the loft window at night. Amazing! Also, the resident fowl (peahens, chickens, roosters) are endearing and friendly/hungry.
