We went on a trip to London, 2 families - 3 adults and 5 kids.
The house's location is great - very close to the underground (and some buses), close to grocery stores, coffee shops, pubs and restaurants, and yet very very quiet.
Kitchen with all we needed (fridge, oven, toaster), nice living room with a big table for our family meals.
Note that there are few floors (my kids weren't used to so many stairs, but enjoyed it still).
We had a great time staying in this house!
