Francesca's place is very nice and comfortable, walking distance from the Tube Station Clapham North (Northen Line) and very close to several bus stops.
The area is very clean and safe. Her place is clean and the breakfast was 100% homemade with a delicious chocolate brownie to start the days :)
I come to London quite often for work and I will definitely stay at Francesca's. No doubts.
