Miki's place was great. It was a little hard to find at first, but it is right across from a Jonathan's and a Izakiya, which would be good points of reference for location. We found it to be very clean and convenient to hop on the metro. NOTE this is not on the JR line, but still a very cheap metro ride. Plenty of hot water for multiple people to shower and space was close to everything in Tokyo. I would recommend this location to groups for sure.
