Unfortunately, my friend and I were greatly disappointed with this airbnb. To start, the bathroom was small and grimy. The toilet paper ran out several times, the hot water would turn off suddenly, and the small garbage can was never changed in the six nights we stayed there. On top of that, we got blamed for clogging their bath tub even though the bathroom is shared between the entire house. Another time, the son banged on the door and yelled "Hello?!" while shaking the door handle while I was brushing my teeth in the evening. My friend (a woman) felt uncomfortable leaving the room after that incident.
Also, the place was noisy in the morning and at night. There was one night where the son was moving things upstairs and throwing trash away downstairs outside our door from 3 AM to 5 AM! We could not sleep and we had a flight that morning. Other nights, we could hear the mother talking on the other side of our wall with someone on speaker phone. We had to play music over her voice because we did not want to hear her conversations.
Lastly, the location was inconvenient. They advertise the airbnb as if it is convenient, but it takes AT LEAST one hour to get to central London from there, often with multiple transfers, and transportation in London is not cheap.
There were more negative experiences we had while there. This was just to name a few. I would not recommend this place at all to someone who wants to enjoy London.
