Traditional Japanese rooms with Tatmi mattresses. The room was very large with big space and a small indoor porch to sit. It also had floor tables and chairs.
It has both inside and outside onsens, 2 for each gender.
I think it is the best place to get an experience in ryokan and onsen. Everything was clean and comfortable. The only one thing that I was disappointed with is that onsen closes at 9.00 in the morning while checking out is at 10.00.
