Abbie's place is very convenient for getting into and out of the city, especially coming from Gatwick. There is a Sainsburys right in Balham and she is very helpful with making room in her fridge and letting you use the kitchen. We had many heavy bags and she offered to give us a ride from the balham train station which was really helpful after a long travel day. The room is small but clean and simple and the adjacent bathroom feels pretty private and is very clean.
