The Hôtel Mona Bismarck by Keys is a private mansion in Paris that can be hired for cocktail receptions of up to 450 guests, seated lunches and dinners for up to 190 and conferences for up to 130. It stands at 34 avenue de New York in the 16th arrondissement, on the bank of the Seine, opposite the Eiffel Tower and close to the Palais de Tokyo.
Seminars and company events
The building offers about 1,400 square meters of reception space, which lets an organiser split a day between several rooms. On the first floor, five reception rooms of 25 to 70 square meters suit workshops, breakout groups and team meetings, while the ground-floor lounges take plenary sessions and dinners. The venue lists conferences of up to 130 guests, flexible lounges for meetings and workshops, wifi and fiber optic internet. A private elevator links the floors.
Beyond meetings, the mansion is offered for product launches, showrooms, private receptions and corporate dinners. Two showroom spaces of 450 square meters each are listed among its capacities, which suits a brand that wants to combine a presentation, a cocktail and a seated dinner on the same site.
Rooms and capacities
The ground floor holds a 450 square meter suite of four historical lounges, reached from an entrance gallery. Moldings, gilding and wooden floors set the decor. The venue describes a suite of three period lounges, a large lounge for dinners and a Chinese lounge that it recommends for morning sessions. The first floor adds the five reception rooms and a terrace. Outside, a garden of about 500 square meters takes cocktails, lunches and dinners.
Stated capacities are:
- cocktail parties and receptions: up to 450 guests
- lunch or dinner: up to 190 guests
- conference: up to 130 guests
These figures apply to the venue as a whole. Ask which rooms are included when your group is smaller.
Catering
The mansion has a catering kitchen. The official text does not name an in-house caterer, so ask which caterers are accepted when you send your request.
History and setting
The house is a neo-classical residence of the 19th century. It was the secondary home of Mona von Bismarck, an American patron and muse of designers from Balenciaga to Givenchy, who left the house and her fortune to a foundation devoted to Franco-American friendship. Keys, a collection of Parisian venues, now operates it for events. A private carriage entrance welcomes guests, and the garden surrounds the house on the Seine side of the 16th arrondissement.
Getting there
Metro line 9 stops at Iéna, Trocadéro and Alma Marceau, and RER C stops at Pont de l'Alma. The Indigo George V car park is the nearest listed parking. Deliveries use the entrance on rue Fresnel, and the venue lists electric charging stations at 23 boulevard Delessert.
