Our family of 4 adults had a wonderful stay in Toshiko's apartment in Shibuya. The apartment accommodated the 4 of us very comfortably and had many small touches to make our stay pleasant. Yoshiko is a great host and responded to any queries we had very quickly.
The apartment is close to Yoyogi Park and JR stations at Harajuku, Shibuya and Shinjuku are a 25-30 min walk away.
The apartment is located in a quiet neighbourhood.
I'd recommend Toshiko's apartment.
