We stayed 3 nights at one of 3 very clean and modern apartments, part of a brand new house where Kana actually lives with her family upstairs. This was great as we always feel more comfortable if we can meet the owner personally.
Kana’s apartment is located very close to one of main shopping streets in the Koenji area, where you can find a lot of nice local shops and restaurants. Supermarkets are also a few minutes away by walk. You could really feel a bit how normal local people live in Tokyo.
The apartment looks as it is shown in the photos. Very clean and functional. Next time we will stay longer at the apartment and explore Koenji more.
Highly recommended.
