Marais
Neo-Gothic drama with 1950s New York chophouse energy. Creams, chestnuts and chestnuts. Persian rugs. Lots of candlelight. Art collected by a fictional world traveler. Feels theatrical without being campy.

Why It Matters
This is the Experimental Group's first true flagship hotel — the group that started Paris's cocktail renaissance in 2007. Designer Tristan Auer, who also did the Hôtel de Crillon and Les Bains, had free rein on a full redesign. Temple & Chapon instantly became one of the city's hardest reservations. And the Roman bath spa is genuinely rare in a Paris city-center hotel at this size.
The Experimental Group's flagship Paris hotel, opened in 2025 inside the former Sinner, a converted Brutalist-era Orange telecoms building. Designer Tristan Auer completely reworked the space around a fictional well-traveled character — ecclesiastical arches, grand chandeliers, jewel-tone textiles — with a consistent New York-meets-Le-Marais thread running from the chophouse restaurant to the cocktail bar. 43 rooms, a Roman-bath spa, and a dining room that's been one of Paris's most-booked tables since opening.
Where You'll Stay
6 room types available
Classic Baldaquin Room
On the 5th floor, these are the most compact rooms in the hotel — but 21 sqm is generous by Paris standards. Grand wooden baldaquin beds dressed in sumptuous linen. Windows look out over the Parisian streets below. Rainfall shower.
Queen · 21 sqm
Deluxe Room
The recommended sweet spot at this hotel. Floors 1 to 4 with Parisian street views. Filled with original artworks and curiosities. Some have bathtubs in addition to showers. Described by Mr & Mrs Smith as feeling like 'your own Parisian pied-à-terre.' All common areas and some Deluxe rooms are wheelchair accessible.
King · 35 sqm
Executive Room
Spacious by any Paris measure at 41 sqm. Courtyard-facing, so quieter than the street-side rooms. Plenty of space to work. Art and travel curios from Auer's fictional wanderer on the walls and shelves. Shower included.
King · 41 sqm
Grande Superior Room
Floors 2 to 4 with city views. A step up to a King bed and more space to spread out. The standard Tristan Auer touch of curated global artefacts and art throughout. Shower included.
King · 27 sqmSuite
The only suite in the hotel, on the top floor with the best views of Paris's zinc rooftops. Ligne Roset cream leather Togo sofas, a record player, stacks of books, a decanter ready on the coffee table. The bathroom features a Serge Gainsbourg-inspired bathtub (black archway, deep red tile lining) plus a separate hammam shower. It feels like a private apartment more than a hotel room.
King · 58 sqmSuperior Room
Spread across floors 1 to 5 with courtyard views. A step up in space from the Classic, each room filled with artefacts from far-flung places as per Tristan Auer's well-traveled storyteller concept. En suite shower.
