Matheew's house is a real London house with a beautiful garden next to the river. It seems to be far from the centre but transport is very easy to reach and the train for example is very fast (15-20m) and offers you to live in a neighbourhood without tourists which is sometimes what you are looking for. We stayed 5 days very comfortably and Matheew waited for us on our arrival until 3am which was a super favour.
Highly recommended! :)
