In which U.S. city is Billy Wilder's film 'The Apartment' set?

Billy Wilder's film The Apartment is set in New York City. The story follows C.C. “Bud” Baxter, an insurance-company clerk whose Upper West Side apartment is borrowed by senior executives for their extramarital affairs.

Baxter accepts this humiliating arrangement because the executives can influence his career. Their favorable recommendations help him rise within the company, but the arrangement becomes morally complicated when personnel director Jeff Sheldrake begins using the apartment and Baxter realizes that Sheldrake is involved with Fran Kubelik, the elevator operator Baxter loves.

The New York setting is central to the film's atmosphere. Its crowded office life, apartment buildings, elevators, winter streets, and impersonal corporate culture reinforce Wilder's story about loneliness and ambition in modern urban America.

Released in 1960, The Apartment stars Jack Lemmon, Shirley MacLaine, and Fred MacMurray. It won five Academy Awards, including Best Picture and Best Director, and was later selected for preservation in the National Film Registry. It is sometimes confused with a Los Angeles-set Hollywood comedy, but its workplace world is distinctly New York.
