We made a memorable time staying there.
The location is just perfect, Koenji station got escalator if you bring your luggages, dont worry. Very easy to reach the home by walking with heavy luggages.
The neighbourhood is really really nice. In the morning we saw some cute toddlers from the daycare in front of the house. Convinient stores, fruits, mwat,easily to buy and we can cook ourselves.
Washing machine is usefull as well. Pocket wifi, just perfect!
You have to try this place! Definitely recommended!
