It is located at 1119 West Bryn Mawr Avenue in the Bryn Mawr Historic District of the Edgewater neighborhood of Chicago, Illinois. The adjacent stations are Thorndale, located about one half mile to the north, and Berwyn, about three eighths of a mile to the south. Four tracks pass through the station, but there is only a single island platform in the center of the tracks; Purple Line weekday rush hour express service use the outside tracks but do not stop.
