Had a lovely stay at this flat for a full week. It's super clean and spacious. Be aware though that the building has multiple units being rented so the pictures might not accurately represent the actual unit. (mostly the same furnishings, just different layouts). I also wanted to confirm another reviewer's note about the speed of the WiFi: It's painfully slow, averaging under 1mbps. If you're planning to work, stream video or do anything other than check email you'll find yourself frustrated.
That said, the neighborhood is great, close to shops and restaurants and an easy walk to the tube. I wouldn't hesitate to book another stay.
