Soho walk ups
Yep, back in the old days, I always lived in suburban areas of London, and always near a tube station, so I could easily get into central London.
Many times, I would be sitting at home and feel like a punt, then take a walk to the tube, and head off "up-west"...
Sometimes, I could visit a walk-up, and be back home in my armchair within 2 hours!
