I stayed for a little over three months at Sally's place as an exchange student, and I wanted a true "local" experience instead of living in a dormitory or a residence/condo type apartment in a busy neighborhood.
Although not in the center of all the hustle and bustle, the place is in a quiet and safe neighborhood, and the place is really close to the Toei line and a brisk 10-15 minute walk to the JR and the Tokyo Metro lines, so going anywhere in Tokyo was easy. Sally was super responsive and considerate for the whole time I was there; and the apartment was clean, quiet, and fully equipped with a kitchen, bathroom, TV, AC, Washing Machine and fast Wifi-- it was just like having my own cozy place in the middle of Tokyo, and I strongly recommend this place for both short and long term travellers.
