The CERN Hostel on the Meyrin site has rooms which can be booked by conference delegates. Please remember to look at the Booking Rules - CERN Hotel Terms and Conditions of Reservation | SCE before contacting them. Please use the following webform to make your reservation. In the webform the hostel management will ask you who your guarantor is, please use Sabrina El yacoubi (sabrina.el.yacoubi@cern.ch) and tick "EUPR external visitor" at the question of your status.
If you decide to stay outside of CERN, we suggest you to pick a hotel close to the tram line nr 18 ( direction CERN) which stops outside the CERN reception (building 33) http://home.web.cern.ch/directions.
