Sayaka's place is the largest that I have stayed, in Tokyo no less. It is very spacious for us (2 people). It can easily accommodate 4 people comfortably. There are 2 supermarkets right around the corner. A MacDonald's right in front of a subway exit. 10 minutes walk to 2 different subway stops on different lines makes it very convenient to get aroind. One line is the Shibuya line which can take you to Shibuya station, almost the center of universe in Tokto. All in all I would recommend Sayaka's place.
