Georgie and Ollie have a very nice and clean apartment in a very calm neighbourhood. From there you will have to walk 10 minutes to get the train in Clapham Junction that leaves you in Victoria station (15 minutes more or less). Although I couldn't meet them because they were abroad when I stayed there, they managed so good to leave me the keys and always were aware if we needed something.
The bedroom is perfect for one or two, with a bathroom inside. Warm water and very warm flat made me forget it was january when we were at home.
I would repeat for sure.
