We stayed here in August 2014 and found the flat to be in very good condition.
Tim met us right on time, assisted us with our luggage, gave us a tour of the flat and a quick rundown on the area. All very informative without being intrusive.
The flat is clean, in good condition and well appointed. It faces Edgware Road which is extremely busy but the windows block the bulk of the noise.
Tim's flat is in a cosmopolitan part of London with easy access to public transport. There are a number of good restaurants within easy walking distance of the flat as well as Tesco, Waitrose and another smaller supermarket.
We would certainly recommend the flat to friends.
