Flat is 7 min walk from Yotsuya-sanchome station, during the walk a number of good restaurants. Very quiet area so Ritsuko insisted to lead us to the flat (she canceled her appointment to meet us when I was late so really appreciate it). Flat is awesome, spacious for my family of five. Tatami room on the ground floor can be a bit cold in the winter (aircon is in the kitchen facing it but Tatami room can still be a bit cold). Second floor is really good with a combination of western style living room (huge TV) and Japanese style bedrooms with 3 beds. I noted a cockroach by the sofa on 2nd floor, but totally expected for a ground floor flat.
