For auction / stash: explore the 'Vampire District' and look for Club Sanctuary. When you go inside the club you'll find a massive safe on the left side of the bar that you can use to access your stash. On the other side of the bar you'll find "The Fence," a character that allows you to access the game's auction house.
If you head back out to the street you'll find entrances to the Mortuary (where you buy different faces, hairstyles), Sergios (where you can get some cool vanities), the Blood Forge (where you can enhance your gear), Esther's (where you can establish, or access your Guild), and there's also entrance to the Subway that leads to the various campaigns otherwise accessible via the Map.
Best wishes!
