Basically i think you want "zone 2 not near tube", or "zone 3 with tube".
Oh and don't believe all the rubbish from the mac carrying nathan barleys that think
all the above places are "too dodgy" - that's just rubbish.
I've got so many friends who've lived in the above areas for years and i've lived
in Peckham for 7 years with no problems.
