I had a great stay at Elizabeth's place. She's the loveliest host you would ever meet, very caring and friendly. Julian, Elizabeth's son who stays at the place is also very friendly and kind.
The room was much bigger than I thought and well maintained. The bed was really comfortable which is exactly what you need on a trip away from home. Location is great, there are all the buses you need to get into the central London within a minute and an underground within walking distance and you can also take the bus (2-3 stops). The neighbourhood felt safe even late at night.
