I currently live in a high cost of living, slightly grim town within commuting distance of London. Rent is roughly on par with a few areas of London and I pay a huge amount of council tax. I'm currently applying for jobs in central London and, should I eventually get one, I'm wondering if it would be better to bleed money in London rather than out here in the sticks. If you were a single twentysomething who preferred a cycle or a very long walk to a tube ride, what neighbourhoods would you look at?
