How is the word Homely used in the story Black Cat By Edgar Allan Poe?

Poe wrote in the opening sentence: "For the most wild, yet most homely narrative which I am about to pen, I neither expect nor solicit belief." I think he was using a double entendre (as Poe liked to do from time to time) with the meaning of both "a description of the narrator's home life" and "an unappealing or even grotesque tale."
