I had a great time at Loic's! The room is exactly as described and the neighborhood is perfect: 2 minutes away from the tube and the bus, a great choice of bars and restaurants, and a fun vibe. Loic's house is on a quiet street and the sunny room overlooks a garden so there is no noise.
Loic is a great host: he's reliable and very friendly. He provided me with a map of the neighborhood and gave me tips on what to see and do.
This will be my go to place in London from now on!
