Ben is a very good host who really cares about you.
However we were a bit unlucky, as our appartment neighbours decided to start the washing mashine at 2am (right in front of our thin door).
In addition there were openings above the window which we were not able to close (Ben tried to help us with this matter). This led to constant noise pollution from the outside.
Regardless of that we had a good time in London and the apartment was very clean and nicely furnished.
