Kana's place was great and had everything we needed. I loved the concrete interiors of the lower floor and the staircase. Felt secure and cozy. Our stay was amazing, would love to be back.
Koenji is also such a lovely neighbourhood. The house is a short walk to the station with many stores along the way. If you love thrifting, this is the place to be. There's decent food choices and also a 24hr supermarket nearby.
