I could not have hoped for a more perfect location. We were able to take the underground directly from Heathrow and exit at a station a block from the flat, where someone personally greeted us and showed us all the amenities of the place. There was activity and shops all around, and so many great restaurants in a 5-10 minute walking radius.
The flat had a large kitchen, with laundry and all appliances we could need. While only 2 bedrooms, there was plenty of room for our family of 4, which includes 14 and 16 year old boys. I would come back and stay here for sure on our next trip to London!
