This place is extremely atmospheric, almost like staying in a museum, e.g.Tokaikan next door. The Seagull Room was lovely with cherry blossoms branches right outside the window, from where you could see koi in the stream.
The hostel is full of vibes and community spirit but it is also quite a budget accommodation. The Onsen is properly maintained. Ear plugs are provided as the walls are thin and you could hear your neighbours. I'd recommend bringing your own eye mask and if you're like me, your own plush towels.
