Stuart is a gracious and considerate host. When my Uber delivered me to the wrong side of London and delayed my arrival by nearly an hour, he was extremely patient and understanding. (If you take Uber, be SURE to specify that the address is in NW6, not Southeast London!) The flat is very attractive, with everything I needed to feel at home--and I had the first really hot bath I'd gotten since my arrival in damp, chilly England.
The location is terrific, with excellent transport, and Stuart has provided a very useful handbook on the flat and the neighborhood around it: things to do, restaurants (I recommend the pizza at Franco Manca), groceries and more. I can't recommend this Airbnb too highly.
