The apartment is very nice and spacious by London standards. It worked well for our family of 4. The host was accommodating with an earlier check-in and gave us a welcome basket of bread, jam, milk, etc.
There is street noise much of the night, especially when warm and Thur-Sat nights, but that's to be expected in a city neighborhood like this one with bars. Very convenient to public transit, Kensington and Hyde Park, other sights. Great value!
