Mary's house is perfect. Mary is a warm and friendly landlord, and very helpful. The single room is absolutely enough for one person, and the house is super clean, including the bedroom, bathroom and the kitchen. 3 minutes walk to the bus station and 10 minutes walk to the central line tube station, and there are Sainsbury and Tesco near the house. The house is quiet as it is not on the main road. I'll stay in Mary's place for next Trip in London, highly recommended.
