In a beautiful 18th-century building, this discreet hotel is as close as you can get to the Palais Royal without actually being in it—which has its advantages: Cross the street first thing in the morning, and you will have the former royal gardens entirely to yourself. If that’s not romantic enough for you, romance oozes inside the hotel, where a Carita spa has a massage room for couples, and a chic bar draped in thick toile de jouy fabrics serves sexy-sounding cocktails like Lipstick (pink champagne, ginger, cranberry, and lemon) and Black Ruby (whiskey, cherry jam, and blackberry liqueur). If you’re celebrating in spring/summer, or just fancy a proper splurge, suite packages include private butler service and luxury picnics. Rooms are classic and elegant; some offer rooftop views of the Louvre from private balconies. Somewhat surprisingly for a 5-star establishment, the hotel’s lunch-only restaurant serves some of the most affordable and delicious menus near the Louvre—just 29€ for two courses or 38€ for three. Eat in at least once.
