Once your application has been accepted, participants have to make their own arrangements for their accommodation. Here some suggestions:
If you would like a room in the CERN hostel, you can contact them directly at Cern.Hostel@cern.ch, asking for a room and giving either Michelle Connor, Nanie Perrin, or Jeanne Rostant as the contact person.
A list of suggested hotels in the area is also provided on the CERN housing service webpage. Special rates are usually applied for CERN visitors.
Public transportation from locations in Geneva, Meyrin or Cointrin is efficient and often a bus pass is included in the price of the hotel.
Notice that the main CERN entrance is in Switzerland, while some of the suggested hotels are located in France. Some hotels on the French side offer a shuttle service to CERN with 24 hours notice.
