DESY Hostel
Unfortunately, the DESY hostel has a very limited capability and we could not block any rooms! You might try a few days before the school if there are any cancellations (in which case you should have pre-booked another room already in a way that you can cancel it on short notice). For the hostel, you can try here:

Hamburg's Culture and Tourism Tax
The city of Hamburg has introduced a special "Culture and Tourism Tax" on January 1st 2013. The tax is based on the number of nights and the price for the hotel rooms and is collected by the hotels. As business travellers, workshop participants are exempted from this tax. This requires, that you bring a special form that is signed by your employer when you check in at your hotel. Please find more information about the tax and the required forms below.
