I stayed in London 3 days with my husband. Paul was very nice and provided us with all the information we needed.
The apartment is located in a modern area, closed to the subway and logistically ok. At night there are no things to do around and you woul need to walk or take the subway to find nice restaurants or places to see.
As for the apartment, it is located at the 10th floor of a building overlooking the train railway and a traffic intensive road on the other. It is noisy, very. We had to choose between closing the window and lack from air (which in summer is crazy without AC) or leave the window open and hear everything happening around.
Pros: location, view, host.
Cons: small room and bed, noise, shared bathroom with the host and his wife.
