This was my second visit to Tokyo and the first with my family, so it was important to find accommodation that balanced location, comfort and value for money, which Yumi's flat did perfectly. The flat is in a quiet part of Shinjuku, close to the metro and 10mins from the nearest JR station (important if you have a JR rail pass) and is perfectly adequate for four adults. It has everything needed, including mobile wifi, and is clean and fresh. The staircase is a little tired and dusty, but this is the only less-than-positive comment and no reflection on the host. All instructions (including navigation and access) are clear and Yumi is a charming and helpful host, who responds swiftly and clearly. Recommended without reservation.
