Parts of SF. Mainly around City Hall.

And no way is it dirty compared to Paris.

Copared to Paris you may be right, but compared to cities of the civilized and modern world, particularly of the US, SF is definately among the worst!

Can't ride a street car without at least one addict on it twitching for a fix, walk down the street without being accosted by some bum, homeless using the bus stops as garbage dumps, urine smell everywhere... sorry I rank SF as one of the ugliest cities I have been in. SF looks great if you are a few miles away looking toward it, but once in it, its a dump... the facade falls. Tagging on everything... adult shops doors wide open for anyone on the street including children to see in, etc... sorry it may not be decaying in terms of its buildings, but its a dump.
