I stayed here during a holiday, and it's a wonderful place to stay if you're here for a brief time. (i.e less than a working week or a few days). The futons are simplistic but comfortable, and as someone who has frequent insomnia, I couldn't remember a better night of sleep in such a small and simple space.
The hotel itself is quite clean, and the staff is always polite and willing to help. I thought it might be louder, with how small it was and how there were quite a few people staying there, but it was actually really quiet and peaceful inside.
There wasn't anything lacking, and it met all my needs as accommodation. Any other hotel of this price would have had free wi-fi as it's (only) highlight. But because of the already stellar experience, it only added to it.
If I ever visit this part of Japan again in the future, I'll be sure to stay here!
