We stayed at Christopher's Flat for 5 days and it probably was my best Airbnb experience so far.
The flat is placed close to a few bus and metro stops allowing us to be everywhere in London in less than an hour.
The flat was very clean and nicely equipped. Many small attentions made our stay especially pleasant (TV with Netflix, kitchen with basic necessities like tea, coffee and sugar, a few tourist guides for the city of London, ...)
Overall a very nice stay!
PS: There are foxes walking around in the neighborhood at night. Apparently it's common in England!
