Sarah's place is really nice. It is a private gated complex in a very nice neighbourhood. Lots of shops and nice restaurants nearby. We really liked being on "the other side of te river", it was less touristy but very nice. Tower bridge is within walking distance and the metro station is nearby. Also there are rental bikes nearby as well. Sarah's was great in communication and responds very quickly. Her place has everything that you need. The kitchen kabinets feel a bit lose so be carefull with opening them.
