We were a family of 8 adults plus a 3-year old and Hiro's place was just perfect. Very clean and spacious, close to the train station that connected us to all the places we wanted to see. Loved the supermarket and convenience stores nearby, too. Check in was smooth and easy, and communication, despite some language barrier, went just fine. Highly recommended and we hope to stay here again next time the whole family is in Tokyo.
