Top floor motel suite
Frank is playing on the image of motels and hotels. Motels are generally considered less classy and are smaller buildings; a “top floor motel suite” is probably still a crappy room on the second floor.
Also, the line expresses the financial relationship between pimp and working woman. He introduces her working in a rundown motel and the pimp reaping the benifits and luxuaries of her labor by living at the top floor suite.
