This was a nice place to stay. Don't expect full privacy because there is only a curtain separating the "restroom/washroom" area from the rest of the place. Also below the restroom sink is in open view to both sleeping areas. So when you step out of the shower you should use a towel to cover up or give a warning to people you're staying with. It all works out though- just wouldn't recommend staying here with people you're not fully comfortable with.
We were here for 3 nights in April and it was freezing. There was a portable heater that we left on (timed intervals) in the middle of the room but because the walls and floors are exposed concrete it was difficult to retain any heat. On the flip side, it would be great to stay during the summer months.
This was a nice place to stay overall because the home is very clean and modern. We were close to the metro, small shops, and restaurants. The bakery across the street has lots of options for a quick bite, same with the Oden stand. We had dinner at a katsu restaurant a couple blocks away that was delicious and very affordable.
