Mary is a very nice and welcoming host, we had a good time staying with her. The room is cozy and has a very nice view on the canal.
Given the location it is a little humid and cold, but there is an electric heater in the room. Close to buses and overground, walking distance from the best Viet restaurant in town.
[There might be other guests in the other room while you stay there, so watch your food ;) ]
