Sourire de Passy is a mansion in Paris 16th arrondissement that hosts working meetings for 8 to 16 people per room and conferences, product presentations, cocktails or parties for up to 50 guests. It has two salons that can be joined, a private rooftop garden, a chef who cooks on site and five bedrooms, and the whole house can be privatised. It stands at 29 rue des Marronniers, in the Passy district.
Seminars and company events
The official site describes a turnkey service for professional and private events. The two salons cover 72 square meters together and receive natural light. Furniture is arranged to match the layout you choose. For working sessions, each room takes 8 to 16 people, which suits a management committee or a workshop. For a conference, product presentation or cocktail, the joined salons hold up to 50 people. The listed layouts for the two rooms together are U-shape 15, meeting 18, cabaret 28 and theater 50. Equipment includes flat screens, a high-definition projector with a large screen, wireless screen sharing that needs no software installation, and secure Wi-Fi and wired internet. The host is the proprietor, who lives in private quarters in the house and acts as the single contact for the organiser.
Weddings and receptions
The site speaks of professional or private events, cocktails and parties, and invites you to describe your needs. It does not mention weddings by name, so a couple should ask whether a wedding reception is accepted. For a family dinner or a private party of up to 50, the salons and the rooftop garden are the working spaces.
Rooms and capacities
Salon Boulainvilliers measures 42 square meters and is the larger of the two. Salon Marronniers measures 30 square meters and takes a meeting of 12. Joined, the two salons make 72 square meters. The five hotel rooms and suites range from 20 to 35 square meters and sleep one to four guests each. A private rooftop garden extends the house outdoors.
Accommodation
Five bedrooms are on site, sold under the name Boutique Hôtel Particulier. Taking the whole mansion lets a group of guests stay where the meeting happens, and the host lives on the premises.
Catering
Chef Brian DeFehr prepares all meals on site. The site says he favors organic produce from the surrounding markets and adjusts menus to the wishes of the guests. He was born in Canada, trained in Chicago, and has worked in French and Italian restaurants and in private Parisian houses.
History and setting
The house is a neo-Gothic manor built in 1909, on land that once belonged to the Château de Boulainvilliers. It sits at the corner of rue Boulainvilliers and rue des Marronniers, in a quiet corner of the 16th arrondissement, close to the Eiffel Tower. The current proprietor previously ran Le Sourire de Montmartre.
Getting there
La Muette on métro line 9 and Passy on line 6 are the nearest stops, and the RER C station Boulainvilliers is close. Paris-Orly and Paris-Charles de Gaulle can each be reached by taxi or public transport in under an hour.
