Pretty awesome place for its price. Placed close to the City Center main stations (10-20 min on the Tube or buses, Zone 2), and the keypads made possible for us to arrive pretty late in the night without any trouble or disturbing the hosts (thank you for your flexibility on this regard!).
On the other side, maybe it's a bit lousy (it's close to an hospital, so it was expected), but nothing that made us uncomfortable or unable to sleep. Also, be wary that the bathroom is shared with the rest of the rooms, and maybe it's showing a bit of its age.
