Keiko's house is an ideal place to taste the authentic Japanese living. It has the Japanese style rooms and all the modern amenities you need. The Japanese style zen garden is also quite impressive. With two bedrooms and large kitchen / living room, the place is quite spacious for our group of three.
The house's location is impeccable. It's about five-minute walk from the JR Higashijujo station, through a pedestrian walkway full of neighborhood restaurants and convenient stores, many of them open till mid night or even 24 hours. The JR lines essentially covers most places of interest in and near Tokyo. The location is particularly convenient if you are a foreigner with a JR pass.
More importantly, Keiko is a great host. She is attentive to all our needs, and put a lot of nice touch in the house. I would recommend Keiko's place to any group of travelers who want to be truly immersed in Japanese culture when visiting Tokyo.
