We reserved two rooms in December 2016 (for two weeks), but only stayed there for one week...and spent one week in Osaka/Kyoto area. Some of the staff spoke limited English, but it didn't matter...all were helpful. The rooms are small, but not surprising for Japan (...bottom line, you get what you pay for). The walls are a bit thin (heard others talking, or snoring...), but it was not a nuisance. There are two showers on the first floor...and never once did we have to wait. Restrooms are on the first and second floor, and were always clean. Smoking is only allowed outside, which is nice as you cannot smell it from inside.
I wish the beds were a bit more comfortable, but it's not horrible either. We were out and about a lot, and only needed a place to crash. It's a little confusing to find the unit (as with most of Japan), but once you're acclimated, it's really simple. There's a vending machine within the building and close by (...yes, hot coffee), and a large convenience store two blocks away. It was rather quiet during our stay (unless you have a noisy neighbor)...personally for us, it was nice being out with all the noise and people, and returning to a calmer environment to rest.
