My Dad and I stayed with Karen for a week. We found her very interesting and easy to get along with. The room supplied was well heated with comfortable beds and bedding. The bathroom is shared but we never had any problem with hot water running out or having to wait long periods to shower. Karen's house is easy to access using public transport (bus or over ground, tube from Tooting). Breakfast was included in the price of the room and this was ample with a good selection to choose from. Very good, near London central.
