We spent three nights at Kaua's place with our two kids, ages 8 and 10. It was AMAZING. The kids loved it and so did we. The house is gorgeous and has so much personality and spirit, and we fell in love with Barrels the kitty. Kaua was very responsive and the extremely detailed directions (and suggestions for local activities) were super helpful! I agree with Kaua's description that if you hate bugs (or cats) this might not be the place for you, but that said, it was very clean and cozy inside, if you are ok with camping you'll be fine with this!
We really just loved getting to stay here. Instead of hotel-type lodgings with no personality, this really felt like having the privilege of experiencing the flavor and vibe of Hana in a way that we love to travel - not as touristy-tourists but as people looking for the sort of cultural experiences we are eager to share when friends or guests visit our town. Highly recommend for anyone who is looking for that sort of authentic beauty!
