The apartment was perfect - surprisingly very spacious, especially for London, and comfortable. The location is great, on a quiet, quaint street but still very close to central Hammersmith - less than a 10 min walk to the tube station and the Apollo. Vicky and her husband (forgot his name, apologies!) were very friendly and accommodating in every way.
My only possible criticism is that the shower isn't very good, but that's such a minor negative - everything else was pretty much perfect.
