I spent a couple of days at James' flat and I must say that it's the PERFECT place to stay in London.
The room was clean and cozy. The neighborhood is really nice and quite and it's well connected by bus to South Kens (49) and Victoria (170). If you are into running, the near Battersea Park is the place for you.
And James was the real plus, he is a welcoming, nice and interesting person to talk to and even share some glasses of wine at the Melanzana restaurant.
I surely recommend him and his flat.
