Do older cities stink and do you like it?

Just curious--do older cities have that odor of industry, aged buildings and sewers, and do any of you consider that foul "smell" a part of those city's character that contributes to the "feel" of the city? I think that as long as a stinkin' city doesn't overwhelm you, but gives you a few foul whiffs of its venerable-ness, such malodorous experiences should be seen as charming and even slightly sexy. Makes you wanna lick the rust right off them aging sewer pipes!>
