We had such a wonderful stay at Sam and Henrietta's home. It's beautifully furnished, tons of natural light and a well-equipped kitchen. While it's a bit outside the center of the city, it is a quick walk to the Kensal Rise overground station and between that and the buses we were easily able to get everywhere we wanted to go. There are great shops right around the corner, and they left a house manual with suggestions for the neighborhood, as well. They were flexible (let us check in early, and extend our stay) and very communicative. Can't recommend enough!
