The building is old, the floor are VERY squeaky, but it's beautiful. The staff are friendly and explain everything, the other guests are generally nice and you can make new friends. There's a kitchen to cook in. There are lots of community seating options on 1F.
It's on the side of the river, wonderful view of bamboo lanterns and reflections at night. The mixed dorm had a comfortable balcony. The private onsen are fantastic, available when it's not being used, no extra fee. I really wish I stayed here longer
