That Funny Feeling (1965)

Love happens in the most unexpected places. Sandra Dee stars as a struggling actress who is embarrassed of where her and her room-mate live, so instead of allowing the man (Bobby Darin), who claims to be an interior decorator, she keeps running into to take her home, she takes him to the apartment that she cleans daily, because she is under the impression that the owner will be out of town for a week, not knowing that the man she met was the owner!
