Very kind staff!
The rooms are very small, but that‘s normal for japanese standards. And as the bed is very high you can store your luggage under it.
The location is perfect. Just 1 minute walk from fukutoshin line and about 15 minutes to shinjuku station. It‘s near Shin-okubo with a lot of restaurants and Kabukicho.
The house and room were clean, they offer cleaning everyday if you wish so.
All in all a very good stay.
