We enjoyed our stay at Keiko-san's place. It was extremely close to the Shimokitazawa area. Lots of food and shops nearby. The area is very trendy and hip! There is an excellent soba shop and Starbucks Reserve, to name a few. The place was quite large for the Tokyo area and had a pleasant feel. The location is on a residential street. However, the entrance is right on the street with some foot traffic, cars, and ambulances right outside. The mattresses were a bit uncomfortable as they were spring-type and thin but perhaps that is how mattresses are in Japan. Overall, it was an excellent stay.
