The Apartment (1960)
While this certainly isn't a remake of "The Apartment" with Jack Lemmon, I would think the script was inspired by it. Lemmon's character was single and his married work superiors began using his apartment for their trysts. For those who like "The Loft" you may enjoy the older movie too.
