MAS Paris, the Maison Action Solidarité, is a meeting and event center at 10 rue des Terres au Curé in the 13th arrondissement of Paris. It rents eight modular rooms for seminars, conferences, general assemblies, training sessions, receptions and shoots. Rooms range from 25 m² for 19 guests to a 400 m² space for up to 400 guests, and most are lit by daylight.
Seminars and company events
The center is organized around work events. Each smaller room is equipped with a paperboard, a screen, a water fountain and a coat rack, and the Hangar adds the equipment needed to run congresses and general assemblies. Wifi is free throughout. The Espace Laffon, the largest space, combines the Émile Laffon room, which seats 250, with the Olivier Laffon room next to it, used for caterer service, workshops and forums. Online, the center shows a live availability planning for every room, which makes it simple to check dates before sending a request.

Le Hangar covers 200 m² for up to 120 guests, with the same three layouts, and is described as suitable for seminars, congresses, general assemblies and meetings.
