It was our first stay in London. Johnny made us feel right at home. He helped us when we couldn't find the appartment, had bought breakfast for us, the appartment was clean and neat and gave us tips about the neighborhood. The appartment was close to the overground (Canonbury) and then you where in 20/30 minutes in the touristic part of London. When you want to travel to his appartment from Stansted, Stratford is a very good option to begin with.
The corrospondence with Johnny before our stay was also good. Very fast responses. Overall: we enjoyed our stay.
