Michel is a small-time thief (Jean-Paul Belmondo), Patricia an American student (Jean Seberg). Start on the Champs-Élysées, where she sells the New York Herald Tribune with Michel at her side. Her newspaper's office at 21 Rue de Berri, where the director Godard makes a cameo, and the Dior windows on Avenue Montaigne are each a short walk away.
On the Left Bank, the Hôtel de Suède, where the long scene in Patricia's room was shot, is two minutes from the lane where Michel looks for a car to steal. Finish in Montparnasse: Le Select and Rue Campagne-Première, the street of the final scene, are about five minutes apart. One day is enough, with a metro ride between areas.
Le Mac-Mahon, the cinema where Patricia shakes off a detective, still shows classic films, so you can end the day in front of a screen. Midnight in Paris also stops at Shakespeare and Company, next to Michel's lane.
