Great place to stay in Hana. While the inn has separate rooms for multiple guests, the place was very quiet and clean. Since most guests arrive late in the day and leave early, we barely saw anybody else. Our room came with a separate dedicated bathroom that was not shared with anyone else. Shared kitchen was well equipped and perfectly adequate for our minimal needs.
I would highly recommend anybody travelling the road to Hana to stay in Hana overnight. It allowed us to travel there in the afternoon and encounter a lot less traffic on the way there and we could enjoy our various stops along the way much better.
Hana Inn worked great for us.
