Buying/Renting property in London: Where would you live?

Okay cool.
I have seen this place, obviously dubios location on a prison, but the price is thus great for what it is! http://www.foxtons.co.uk/property-for-sale-in-brixton/chpk2589800
Aside from this place directly, is this 'section' of brixton, south wise going to be okay? It's just, don't go north up from the tube really...

We live just behind the prison - safest place to be! Nice community round here.
