The location is fantastic. Very close to the tube, and very close to restaurants, with a supermarket around the corner. The room is quite nice--bright and airy with the windows open.
I never met Paul, but his partner, and especially his son, were nice.
A couple things to note: The bed is actually a futon and very low to the floor, which could be a problem if you have bad knees or other mobility problems. (It also has a pretty thin mattress.) Some of the little touches you might be used to from other airbnb stays weren't there: a hair dryer, toiletries, light breakfast snacks, nice towels. (There were towels, they were just pretty thin.) Which is fine as long as you know and come prepared.
