Completely different now. Areas of London do change very quickly. I lived in Brixton for a year and there was a street where the houses were going for £500k+ that apparently 10-15 years ago were crack dens.
Yes.....worked in London for over 25 years, interesting to see over the years. Can still vaguely remember parts of Canary Wharf when there was nothing much more than disused buildings some time after all the construction really got going in the late 80s.......whole of the Isle of Dogs is pretty nice now !
