I was a relatively long-term guest at Sarah's apartment and I can definitely recommend it. The place was as advertised and is very conveniently located - very close to the Edgware Road tube station and with 3 supermarkets within walking distance. Sarah was a great host. She was often away while I was there, but this did not cause any problem at all, as she always replied swiftly to my messages and for more urgent matters her relatives were there to help.
