Quiet everything was great (communication, location, flat in general). The bathroom is very small. For me (7 months pregnant) and my taller husband it was quiet narrow. The chairs in our flat should be replaced.
By underground (Queens Park) you need about 15-20 minutes to the center of London. A few steps from the flat you have everything you need (supermarket, pharmacy, restaurant, cafes).
Altogether it was a great stay at your flat and I would definitely recommend your accommodation.
