Stayed there for 10 nights and I must say the apartment was really clean and neat! Location was perfect as well with it 5-7 mins away from Hatagaya Station.
There's plenty of food stalls around the area and if you need, a supermarket is near the station too.
To get to town you could take the Keio-Shin line from Hatagaya Station to Shinjuku Station (2 stops) and from there you could get to pretty much anywhere inTokyo without any problems.
Overall, it was a great stay and would recommend it to anyone looking for a nice and comfy place to stay while in Tokyo!
