Accomodation
The address of the venue is Mehrzweckhochhaus, Bibliothekstraße, Bremen.
There are many hotels of all categories distributed over Bremen and usually the travel time is rather small (<30min) in particular if you are on the right side of the river. You can book them via www.booking.com. The districts “Mitte”, “Schwachhausen”, “Finndorf” and “Das Viertel” are especially well connected.
