As a student through to my late twenties I loved living in central London. Student accomodation, bedsits, shared houses: Moorgate, Kilburn, Islington... I cycled to work at Marble Arch.
Everything you could want on tap, from parks to nightclubs.
But somewhere around age 26,coming back from a walking holiday in Cornwall, I suddenly realised how crowded, noisy and dirty it all was. I moved to Cambridge and loved it, though I'm now in Cornwall, and loving that too.
I enjoyed my time in London, but I think I've done my time in London. I wouldn't want to move back.
If you're going to do London, it's really the centre that is the draw. Being miles out in the suburbs, for me, would have been neither one thing or the other.
