Hatagaya is close to many places, either from Shinjuku by train or Shibuya by bus you can reach and voila, the whole world is reachable.
Place was clean, however it’s really compact. If you need more open space, look for something else.
Sofa bed is actually not comfortable.
What worked for us is pocket WiFi router, it really makes your like easier and make you connected to the world even on the go.
If you take it from outside, you have to shell out extra money. Thank you
