London Acting Classes

Hey all,

I'm moving to London at the end of March, and I'm keen to get into some acting classes. I've got a theatre degree but have been travelling for a few years and am feeling a bit rusty. I'd like a class that isn't aimed at complete beginners, but not a complete university course.

Can anyone recommend any schools, preferably ones where they've attended classes themselves?

Thanks heaps.
