The hot spring should be hotter in my opinion but the other guests seem to enjoy it the way it is.
Not sure why people left negative reviews about the food. I enjoyed it a lot.
People may complain about the smell of the room but that is coming from the tatami mat. They have a pleasant grassy scent that I enjoy. Not everyone's cup of tea I suppose. If you desire modern conveniences, they are provided but do not take the ryokan as a western establishment. If you want to experience old Japan, the ryokan is the place to be !
