Can see myself moving out to the counties in the not too distant future, but however London has changed in recent years, I only have to visit the west of scotland (where my parents live as that’s where my mum is originally from) to realise that for all its faults, London isn’t a bad place. The south east might be over-priced and over-populated, but it sure as hell beats a lot of the depressing down-on-their-luck places up north. I love the south-east and I’ve no intention of living anywhere else. 
I work in Kings X and there is ample bike parking on the south of the Euston Road. Don’t expect much to the north yet with all the chaos of the building works.
