The airbnb hut was small but effective, it does for 4 adult sleepers in and when we were there we were only using it to sleep which I reccomend.
There was, however, disturbances through the night and people coming and going through the back gate and into the garden where we were staying. If you want to visit Central London, this airbnb is quite far out of city, in North Acton and takes about 30-40 minutes on the tube to get into Central London.
Otherwise, the host was very quick at responding to messages and accommodating to our needs.
