All in all I had a few very nice days in London and in this lovely small home.
However, it is not an actual "privat room", because it is just splitted up with wooden panels from the rest of the ground-floor. For me this was not a big deal, but you need to know that before arriving.
There is butter, bread, olives, cafe, eggs, milk and tee for breakfast. The cleanliness was pretty good.
I would stay there again.
