We had a great time staying at Kana's place. It's a perfect location - on a very quiet street but just one block from a main Koenji street with lots of shops and restaurants. As the location is between Koenji and Shin-Koenji, you have easy access to a number of train lines. Her place was modern, clean, and comfortable. As Kana lives upstairs, she is responsive should you have any questions or additional needs. Would definitely consider staying here again.
