We passed a beautiful weekend in London. We've been received by Paul who has been quite available for our requests. He live just upstairs with his wife Victoria and their children, but we felt like we were alone because of their discretion.
Paul and Victoria's apartment is very large, even too large for two people (but the price is still interesting), and really full of accommodations. The area is nice and full of little restaurants, maybe a little bit far from the first metro station (but this maybe normal, we're in London...).
We recommend it anyway.
