A promising young designer puts her stamp an eclectic Parisian stay.

Up-and-comer Dorothée Meilichzon—who won Designer of the Year at Maison & Objet Paris in September 2015—has a real eye for pattern. At Hôtel Paradis, she employed some 57 different wallpapers throughout the interiors. For her next act, she’s dispersed a patchwork of motifs across the carpets, tiled floors, and walls of the new art nouveau-style Panache, in Faubourg Montmartre near the Grands Boulevards. It’s an astute visual solution to the complicated triangular floor plan of the corner building (New York’s Flatiron Building was one of Meilichzon’s references). The 40 rooms are akin to an assorted bag of jelly beans, each one dissimilar in shape and size—some have annexed sections of the corridors or asymmetrical alcoves around the stairwell. Miniature lounges, triangular sofas, and geometric mirrors make for an idiosyncratic design that gets added style points for steel-and-cane headboards and some Meilichzon favorites, like vintage telephones and Bauhaus light switches. The ground-floor modern bistro is run in partnership with restaurateur David Lanher, whose innovative rethinking of classic French cuisine has earned him a devout local following—the reason the Parisian clientele suspend their apprehension to hotel restaurants and pack the place nightly.
