Only two places in London for a southern hemi to stay and that is Shepard's Bush and Wimbledon.
Tooting is nice and close to Wimbledon but you need to speak Malayalam or Punjabi, anywhere affordable near Shepard's Bush is a Sh!t hole, even non affordable is pretty grim sometimes

Hayes/Heathrow/Yewsley/Feltham/W Drayton all affordable but like the 80's bronx in places, pick your area wisely

Lots of south Africans Zims in Kingston area as it is good for West London, Wimbledon and Richmond which are all good nights out and covered by night bus.
Always Croydon............
