This place is magic. The courtyard of an old palace, right next to the Louvre, has some of the hippest, most beautiful shops, set in this stern, monastic ambiance. Incredibly charming, and considering it's just next to the Louvre, surprisingly hidden! Expect to find beautiful vintage, old war medals, but also Marc Jacobs and Stella McCartney, as well as the stunning Serge Lutens perfume boutique.
