I stayed at Alison's place for about 5 weeks in May-June, and it was a great experience. Alison contacted me in advance and sent me directions to find her place, so it's convenient for someone who is new to London. The room is bright (lots of sun when the weather gods permit) and looks out to the back garden, and there is plenty of space and storage - Alison was also kind enough to provide towels and linen. There is only one bathroom, but we worked around a schedule, and the kitchen (with the washing machine) is just next to the room. The house itself is in a lovely location - in a quiet, leafy neighbourhood just off the main road (which has plenty of shops), and only a little more than five minutes away from the tube station. The area has excellent bus and tube connectivity with central London, and makes for a good place to explore the city. Alison was always helpful, and she and her son made me feel very welcome in the house - I would highly recommend staying here.
