What wasn't clarified upfront, either in the listing or my initial communication with Mo, was that the property had 4 bedrooms, 1 for the hosts and 3 for guests (although they did have 2 bathrooms between them). Consequently the house felt quite lived in, with a slight hostel-like feel. The common areas also had varying levels of cleanliness, depending on their usage.
Hakim, who lived in the house and managed the airbnb (again, not informed until after I had booked and specifically asked about the check-in process) is a perfectly nice guy, very responsive and handled all our requests. The room, as others have stated, is basic but functional and offers good value for money. The house itself is centrally located and is well connected by bus to central London.
