Before I moved to Chislehurst and started 'Chislehurst Driving School' I lived in Charlton, and was unsurprisingly known as 'Charlton Driving School'. One of the great things about living in the area is being close to Charlton Lido - a 50 metre heated outdoor swimming pool. I go 3 or 4 times a week It's easy to get to by car or bus (161 from Chislehurst, via Eltham). If you get the last swim of the day it can get quiet, which is nice if you don't like bumping into other swimmers. Highly recommended if you haven't been.
I teach in Kidbrooke, Blackheath and parts of Charlton, depending on timings, so if you're in that area please call for a chat.
