Nice staff and service. There are many restaurants nearby, you also can find Donki, supermarkets and other small grocery stores within a short walk. convenient location but not very crowded as city center.
I would say this hotel might be the best choice if you need to stay in Kitasenju area. Very closed to the JR Kitasenju station(~6 min walk), lots of restaurant and convenient stores nearby. The room is very clean. Staff is very friendly and helpful. Breakfast is also fine. I will still choose this hotel when visiting Kitasenju next time.
