The conference and summer school take place on campus in Talence, officially a suburb of Bordeaux, but you will be hard pressed during your 15 minutes tram ride on the B line to tell where Bordeaux ends and where Talence starts. So you have the choice to stay at a hotel in the city centre or next to the campus. The Informatics department has a list of hotels where university guests often stay, or try the tourist office or any modern way of booking accomodation.
