Oliver and Hellen's place has great value and is in a vibrant residential neighbourhood off the regular tourist track. They were good and friendly hosts and we enjoyed our time staying at their house. It took us about 25 minutes to walk to the nearest train station from the house, but you can also take the bus. There are grocery stores and cafes in the area that are easily accessible in a 5 minute walk, and you can find anything you need easily. This place provides a good opportunity to see a side of London you might otherwise miss. Thanks Oliver and Hellen!
