Great room in a nice part of London.
Joanna was easy to get hold of and made me feel very welcome: a far cry from the many souless (and ownerless) properties you find on Air BnB these days.
As described, you have the ground floor to yourself, but Joanna was available for help/advice when required.
The only negative was that it was 15 minutes walk to the nearest stations. The positive side to that though was that it was a quiet residential area.
