We were very satisfied with our 7 night stay at the Minn Nihonbashi hotel, it was perfect for our family of 4. Spacious, clean, and it had everything you need for an extended stay (refrigerator, microwave, stove, sink, cookware, dinnerware/utensils, and washer/dryer). The extra area (multipurpose room) had its own TV and had a room divider, which was perfect for the kid's room. Close by convenient stores (2 minute walk), restaurants (5 minute walk), and subway entrances (5-7 minute walk, depending on the line). Very reasonably priced as well.
We will most likely will be staying here again on our next visit to Japan (Tokyo area)!
