Ah, I forgot about that scene in Headhunters. That would make it somewhere on the first floor, and that would make more sense since a parlor is suppose to be a reception room, if it's right next to an entrance.

And looking at the images of Stan's office again, it has a slanted ceiling and outset windows, suggesting it's on the second/third floor.

As for the cellar, I think anything down there is related to Stan's secret (or covering it up), and that he wouldn't want to give anyone reason to go down there.
