We loved the Bamboo Bungalow!
The space is very private, including the outdoor shower. Everything in the kitchen had cute labels. We loved the fresh fruit and flavored ice cubes. Everything was very clean. Everything you might need is there to borrow (boogie boards, sunscreen, umbrella, guide books, etc.). We watched the sunrise from the rocking bench up on the hill one morning and it was great.
The location is convenient to the highway. It was easy to get down to Volcano National Park or up to Hilo.
The one caveat is that the frogs at night are pretty loud. I was ok because the noise is rhythmic so I could make it feel soothing. My girlfriend had a bit of trouble falling asleep though, but it wasn't too bad. Earplugs are provided and she tried those but they didn't help that much.
