To be honest, this mission is really lackluster, even for its age.
It´s short and not really well designed. Issue is, you are likely to run into the house of the antagonist here without even knowing you should be there, because your informant is located farther away. So, if you get to him, you know the things he will tell you already.
It doesn´t matter that much as it doesn´t break the mission fortunately, still not very intuitive.
Some loot is also hidden in a kinda obvious and frustrating spot. Guess the loot goal is optional for a reason. City feels overall rather empty, only "non-doors" and a few hidden loot pieces. That´s it.
Would call it a poor mans Assassins, even with thugs coming after you when you are done. Mission has custom intro(which looks awful) and outro(okayish, but nothing more).
Wouldn´t recommend it.
