Dark Fantasy urban campaign

[King In Red]

Hello everybody, I wanted to ask you if you know of a resource or adventure path or module to create an urban campaign of dark fantasy genre.
I'd like a dark setting Bloodborne style, with a corrupt city full of criminals, thieves and murderers.
A city like that seen recently in the reboot of the video game Thief or Dishonored, with a hint of gothic horror.
some advice?

Any path involving the inner sea areas of Ustilav, or the river kingdoms might be a good start, I have not had extensive experience with the modules. But the inner sea guide describes Ustilav as the equivalent Transylvanian location. The River kingdoms are thieves rule, lawmakers are token.
Honestly there are a lot of great resources in the inner sea guide in general, with histories, races, plot points, maps and all kinds of helpful world building for that region.

The Council of Thieves AP covers a lot of the "dark urban fantasy" look.

The first two modules of the Second Darkness AP should give you a good look at grim urban fantasy (perhaps not "dark fantasy", more like "low-life criminals get involved with Things Man Was Not Meant To Know", though after that the plot goes somewhere else and never returns to Riddleport.

Adventure Paths:
Tonyz's suggestions are good.

Carrion Crown goes full throttle on the gothic horror, so it might not fit your needs.

Another that might actually do pretty well would be Curse of the Crimson Throne. It's definitely in a city that's going straight to hell.

Modules:
I don't have great advice here. It's likely there are some, though.

Resources:
My two favorite city books for Pathfinder are City of Strangers and Magnimar, City of Monuments. Kaer Maga (City of Strangers) is probably the better bet for a dark fantasy setting, but there's enough going on that I wouldn't necessarily start there.

I've also heard good things about Green Ronin's Freeport stuff, which may be up your alley.

Cheers!
