Stoop Lady?

So I never had a problem with missing the group flight and showing up after everyone else... just me. I looked at it as an adventure. I did fine jumping in a cab in finding the flat (not a chance I was lugging a 150 lbs of luggage through the tube). No one was home when I arrived, though, and the place was locked! The cabbie pulled away and left me on the stoop with my 4 bags. I tried to ring every room, but everyone was out exploring. Figure maybe I'd just sit there and read..
