My wife and I stayed in Sarah's flat for three days in March 2013. We were very comfortable and would recommend it subject to the following observations:

Pros: The flat is just what it appears in the photos. No fish-eye distortion. It is spacious and adequate for two. The living room is sunny and airy. The apartment is quiet. The hot water works well. The kitchen is well supplied. The heating was adequate.

The welcome gesture of providing a few provisions was greatly appreciated as we arrived hungry and disoriented.

The flat is five to ten minutes walk to a tube station and to a Waitrose supermarket. If you are going to cook for yourself, the latter is a big plus.

Cons: My wife, who was on her first visit to London, found the location a bit too suburban for a three-day stay. She would have preferred to be closer to or in the west end. I didn't share this qualm. Having been to London dozens of times, the most important thing for me was that the flat was close to a tube station.

This was my first time using Airbnb and I have one peeve. The final price of the stay, after adding cleaning and booking fee, comes to about 20% more than the initial offer price. It is still reasonable for London. But it comes as a bit of a bait and switch to the user. I would urge Airbnb to be more transparent.
