I really recommend this place to visit London! John was really helpful, he answered all our questions quickly and even sent a detailed message about the appartment and all necessities around. Very good organisation.
The appartment is very spaceful, perfect for 6 personns (I traveled with my family), very clean, luminous and with all confort needed.
You have some shops around, a nice park to walk.
It was just a bit far from the center of London.
