London SE5. I can't seem to find a Camberwell stn, either train or underground, but I recently travelled on bus 176 from Forest Hill. It went through Dulwich, Camberwell, Elephant & Castle and Waterloo Stn.
SE of the Oval, E of Stockwell & Brixton
I've just been into the BT directory enquiries site and called up this map

I hope that the link works!
There isn't a tube or train station. The nearest tube is Oval (Northern Line), approx 15 mins walk from main shopping area. There are loads of buses/night buses. You can download a lot of bus timetables here http://www.londonbusroutes.net/routes.htm
