Very close to Paris, just outside the RER C station, with parking if you go by car. There is a bar at the reception.
The people who work there are very nice, cooperative, flexible and friendly.
The great hall is large, of course. Can accommodate a lot of people. Lighting and sound device well suited to the size of the room.
Multidisciplinary; they offer a variety of activities / shows, but i have little information on that, you can check their website.
