Rei will warn you about how far this apartment is from Tokyo, but trust me - It is worth the travelling time.
The apartment is warm, beautiful, and extremely comfortable. You will find everything you need to stay in Japan either for short term or long term trips.
The only drawback is the distance from Kunitachi station. A bus comes every 20mins, but if you choose to walk - One direction has many Izakayas, while the other has interesting general stalls.
Rei is also a very involved host, and will check in on you periodically to see if you are doing okay, and to offer her advice and recommendations.
Overall a very good place to stay! Would stay here again definitely!!
