Accommodation is not provided by the school, except for scholarship holders, whose accommodation is booked by the organisers. All other participants arrange their own accommodation, after receiving their acceptance email.
Where to stay. The most convenient places are near the RER B stations close to the campus (Orsay, Bures-sur-Yvette, Gif-sur-Yvette, Le Guichet) or in Massy and Palaiseau. Staying in Paris is also possible: choose a place close to the RER B line, and allow about one hour each way.
Beware of accommodation scams. The organisers will never ask you to book or pay for accommodation through a third party. If an agency contacts you claiming to handle housing for the school, do not reply and let us know.
