If your vision of Montmartre involves secret little cobbled lanes and old townhouses with tree-filled gardens, this chic, arty hotel is for you. To get to it, you must buzz in from the street, then take a narrow, private path—Passage de la Sorcière (aka the “witch’s alley”)—to an elegant former mansion. Each of the five suites was designed by a different artist: One evokes a fancy bordello, with jewel-studded velvet walls; another has psychedelic floral wallpaper and stunning views over the garden; all are sumptuous. For extra pizazz, the loftlike, top-floor suite is awash in natural light and flaunts an open bathroom with a clawfoot bathtub. Into food? You may want to consider dining in: The hotel’s on-site restaurant, Mandragore, offers exquisite French dishes with a modern twist, and serves afternoon tea (Wed–Sun) in an olde-worlde courtyard—a glorious treat on a sunny day.
