Mrs. Jennings owns a townhouse in Upper Berkeley Street, near London's Portman Square, which houses the Dashwood girls during the course of the novel. We know that her husband had a career trading in the City, so it’s likely that the townhouse was a purchase later in life.
Architecture and Decor
When Elinor and Marianne arrive, they discover “The house was handsome, and handsomely fitted up, and the young ladies were immediately put in possession of a very comfortable apartment. It had formerly been Charlotte's, and over the mantelpiece still hung a landscape in coloured silks of her performance.”
We are given few details about the rest of the house, but we do know that the girls receive many callers while in town and Mrs. Jennings hosts several dinners, so it’s likely the public rooms are quite large.
Staffing
Mrs. Jennings mentions a Cartwright who must be either the butler or the housekeeper. We also know that Mrs. Jennings has a maid she calls Betty whom she seems to know quite well.
