The apartment was clean, compact, and comfortable. It provided all I needed during my 3 weeks trip (Washer, iron, heater, fridge, freezer, microwave, dishes and stable Wifi).
It is not too far from the train station to Shibuya (10 min walk) and had several convenience stores near by (you can also try the Peacock on the way back from the station which is bigger or if you want to buy bentos).
The area was calm and pleasant.
Kumina is very welcoming and reactive. My arrival went smoothly thanks to her clear instructions and she answered all my questions rapidly.
I highly recommend !
