It is extremely difficult to get a hotel room in Paris during the summer period. A list of selected hotels can be found here. Several of these hotels are located near the conference venue.
If you book a room further away, please note that it is very easy to get around in Paris using public transport.
If you want a direct connection to the conference site, we recommend to book a hotel around the stations of Line 2 of the Subway and Line C of the RER.
