Well equipped, comfortable house. Very good transport to the city. Beds are good, cat is friendly. Lots of shops and pubs in the neighborhood, but also nice parks for walking or running. Olympic Parc on a few miles distance!
The only disadvantage was the building work at the neighbor's house. Noise starting at 8 am. Sophie mentioned it a few weeks before we arrived, which was kind, but we had no possibility to look for an alternative.
Apart from that, Sophie's house is the perfect place for a family to stay and discover London.
