Experimental Marais

Childhood friends Olivier Bon, Pierre-Charles Cros and Romée de Goriainoff founded the Experimental Group with a cocktail bar in 2007 and built an entire world from there — hotels, restaurants, wine bars, across Paris, London, Venice and beyond. When their first Paris flagship hotel opened in March 2025, it arrived as the most personal statement yet. Interior architect Tristan Auer conceived the 43 rooms around a fictional wanderer who leaves his souvenirs, trinkets and art on the walls for those who follow: objects from far-flung places, grand wooden baldaquin beds, artefacts arranged as though someone actually lived here. Rooms range from 21 to 58 square metres, the top-floor suite overlooking winding Parisian streets with a hammam shower and bathtub. Downstairs, Temple et Chapon serves in a refined dining room; the American Bar channels a New York that Paris has always quietly admired; and the spa below offers Susanne Kaufmann treatments in a Roman bath setting. Le Marais moves fast. Inside, everything is perfectly still.
