I have been staying in Mariam's house for over 2 months during my internship in London. The house is very clean and located in a quite area near Willesden bus garage. The underground station Dollis Hill is only 10 min away and the bus station is even closer (you can choose from a variety of bus lines i.e. 6, 98, 52 - also night busses).
Everything was as advertised. Mariam is such a lovely and friendly person and she really cared about me. I was allowed to use the kitchen and the living room and the garden as well. I really enjoyed staying in her house and I would highly recommend it to everyone.
