Roger's Apartment is an apartment unit in the Washington Mews occupied by Roger Baugh.
In the summer, after the New Ghostbusters disbanded, Janine Melnitz was staying the night with Roger and trying to find a movie to watch on TV. All of a sudden, Janine was catatonic and bled Yellow Slime out of her eyes. Roger rushed Egon Spengler back to the apartment to help. When a dose of positively charged Psychomagnotheric Slime failed to yield any change, Egon and Roger guided Janine down the elevator and took her back to the Firehouse.
