Spent ~10 days here: Everything is pretty much as it is advertised; the room and house was generally clean except for some odd spots, all appliances work. Yes, the room is small and there is the restaurant fan, but those are things that are throughly communicated beforehand, so you know exactly what to expect. All in all my stay was very comfortable.
The biggest positive of this AirBnb is its absolutely stellar location: being so close to central London is really convenient.
