To reserve a DESY hostel room, please read the information and fill out the registration form on the DESY hostel webpage.
Important: In the field "Additional Text" please enter "Helmholtz Allianz". If you do not receive a confirmation of your reservation by email within four weeks, please contact the local organizing committee. There is only a limited number of rooms, so better book early (first come, first serve).
If you don't want to stay in the hostel, or if it is already fully booked, here is a list of hotels:
A number of rooms are available at the ETAP hotel located here (single 43 Euro, double 53 Euro, breakfast 6 Euro). You will need about 30 min with the bus to DESY.
Cheap rooms might also still be available at the Schanzenstern Altona or St. Pauli.
Closest to DESY but more expensive is the Novotel Hamburg Arena.
If you prefer a different hotel, you can find here a list of hotels in walking distance or with good public transport connection to the DESY site (courtesy of the DESY Theory Secretaries).
