It was an absolute pleasure to stay at Kanako's house. She and her daughter immediately made me feel at home in their beautiful house. Although the house is shared, the room provided plenty of privacy. Kanako tries to make you as comfortable as she can and nothing is too much for her. Also she speaks English so it's easy for foreigners to communicate.
On a map the location might not seem convenient but it actually is very convenient as it is near several trainstations like Shin-Daita (5 mins walk) for Shibuya and Daitabashi (10 mins walk) for Shinjuku. Also Shimokitazawa is within walking distance with loads of shops, cafe's and restaurants.
If you want to experience the local life in Tokyo, you should definitly book a room at Kanako's house!
