The curved staircase, embraced by a wall of mirrors, gives a nod to Coco Chanel’s apartment on Rue Cambon. Upstairs in Grant’s aerie, furnishings scouted in France and Italy imbue the space with quiet elegance. “The studio is an immersive and intimate experience which embodies the design, intimacy, and warmth of a contemporary Parisian apartment,” Grant says, adding that she hopes clients will feel at home in the space. With only two treatment rooms and a private feel, doing so is easy. Plus, considering the glow-giving results of Grant’s signature facials—which incorporate results-oriented technologies such as diamond-tip microdermabrasion and light therapy—it’s tempting to move altogether. (One can dream.)
