We had a wonderful time in Gabrielle's flat. It is very well located being very close to all amenities, and several tube/train stations are within a few minutes of walk. Upper Street is also only 10-15 min walking distant through a very nice residential neighborhood with a few hidden gem pubs and little independent shops!
The flat is spacious for 2 guests, is bright, quiet and very well equipped. While Gabrielle could not meet her personally, the communication prior to our visit was very efficient, and she organized in advance that we would be welcomed by the husband of her daughter, who was very helpful and friendly. We certainly recommend this place as a great base to spend a nice weekend in London!
