Our stay at Victoria and Evan's house was wonderful. They are very kind and helpful and made it very easy for us to reach them by sms or message on airbnb.
You can quickly get to most of the attractions in Central London by tube, as the Kennington station is at a 5 mins walk distance. In the area near the house there are also a couple of supermarkets and a big park.
The house is very spacious, with two double bedrooms, a room which can be used with a single bed and another single futon. The presence of 3 bathrooms is also very comfortable.
I'd definitely recommend this house and I hope to stay again there.
