Fictional address of 'That Girl'

That Girl is an American sitcom that ran on ABC from 1966 to 1971. It stars Marlo Thomas as the title character Ann Marie, an aspiring (but only sporadically employed) actress, who moves from her hometown of Brewster, New York to try to make it big in New York City.

Her apartment appeared to be set right off the east river in the upper 70s or lower 80s in-between York Avenue and East End. In the episode entitled "Señorita," she lists her address as 627 East 54th Street.
