This is the address of the brothel, and it's the mistress's. She's been drinking heavily, and she's worried about what's going on with Edward and the vampire. She wants to know where they're going, but she can't figure out how to get back to her mansion. She tells the housekeeper to get her reward from the maid, and then she tells the painter to come work for her, because she doesn't want him to be a prostitute. The painter is all, "I'm not a prostitute, I just want to make more money" . He's not even thinking about escaping, he just wants to earn more money.
