Kazutomi's place was everything that he has described. When everyone talked about how steep and small the stairs were, they were right. It was difficult to get our huge luggages up and down... But we made it work. His place is about 10-15 minute walk (depending on how fast you walk) from Ogikubo station, it's around 30 minutes to get to Tokyo using the subways. Everything we needed was there and he was very responsive to any questions I had. Thank you :)
