The apartment is very spacious for Tokyo standards, nice large living room and upstairs bedroom. It is only a short walk from Nippori station, which is very well connected and will take you to most tourist sights (ie: Shibuya, Shinjuku, Tokyo Tower) within 20-30 minutes.
There are supermarkets and convenience stores around the block, and many small restaurants. The neighborhood is very quiet.
The hosts were very friendly and quick to respond whenever we needed help.
I, however, had a few issues with this apartment:
1) Some of the things are very old and could really use new ones, such as towels, bed sheets, and linens. The kitchen could use better silverware as well.
2) The upstairs bedroom has 2 singles beds pushed together to make one large bed.
3) The tatami room has a very thin mattress that is very uncomfortable to sleep in. I had to ask for more comforters to layer them on top of the mattress.
4) The downstairs bathroom and shower had a constant smell of urine, and it is right next to the kitchen, which is very unpleasant.
5) The wifi was unstable and would just not work sometimes. The pocket wifi was pretty much useless when I took out on the street.
