The symposium will take place in Antwerpen, Belgium, at the University of Antwerp, campus Middelheim, building G "Wiskunde-Informatica". (Street address: Middelheimlaan 1, 2020 Antwerpen.)


The city center of Antwerp boasts a large number of good hotels. For convenience of transportation, take a hotel close to the central station. Some hotels very close to the central station are the Tourist**, the Florida***, the Empire***, the Agora***, and the Atlanta***. You can find all of them on

One good hotel we can personally recommend for its friendly staff, it is 500 meters from the central station, is Hotel Colombus. They give a special price for university guests; at check-in or check-out, just tell them you are visiting the university and they will give you a hefty discount.

Another hotel we can specially recommend, although it is not close to the central station, is Hotel Elzenveld, for its wonderful building, atmosphere and location in the city center. They also give a special price for university guests. Moreover, you can easily take tram 7 in front of this hotel and get off at the same stop "Koninklijkelaan" as that of tram 15 mentioned above.

For the young or budget-conscious traveler, there is also a great youth hostel in Antwerp belonging to the Hosteling International quality chain of hostels.
