  • Hotels in walking distance to the University of Liege, Rectorat (first day) in the city centre (~ Opera): there are many options going from apartments, small boutique hotels and the larger ones: Pentahotel, Van der Valk Congres (other side of the Meuse, nice walk of about 10' in the morning), Selys.
  • Hotels convenient for transport, near Guillemins are a good option (late arrival, easy bus connection to center and campus): Ibis Styles or the Yust hotels as probably good/safe options as they are brand new and part of chains. This is the easiest in terms of transport, but requires a 20' walk to go to the Rectorat; for the second day, there are the buses in front of the hotel.
T​raveling to Sart-Tilman Campus (second day):
  • For the second day, the best option is to take the bus from Guillemins station (48 or 58) and stop at Polytech. Taxis are available for around €25 - €30. For bus service tickets are available with the app installed.
Arriving to Liege:
  • for almost every one, and especially UK, France and Netherlands, the best is to go to Bruxelles-Midi, either from the airport (Zaventem) or direct by train. There are fast connections from UK (Eurostar), from France/Netherlands (Thalys) and Germany (ICE), next to regular trains. From Bruxelles-Midi, there are direct trains to Liège Guillemins once an hour (Liège-Welkenraedt, about 1h). For tickets : (NL/FR/EN). Belgian train tickets are not on reservation - they are valid for one ride during the whole day. Train conductors accept electronic tickets (obtained via mail, or a dedicated app), no need to print if a bar/qr code is present.
  • another option is Brussels-South (Charleroi) airport. From there, you there is a bus shuttle 1 (6 euro, buy ticket before boarding on electronic distributor, every 30') to Charleroi-Central train station; from there you have a direct train to Liège Guillemins (Liège-Herstal, 1h30 travel) every hour.
  • for German participants, there is in fact a much better option since the ICE to Brussels (from Cologne) stop at Liège Guillemins.
  • for people staying in the city center, there are a few small stations in the city itself. In particular Liège Saint-Lambert is close to the Opera. You will have to change trains in Guillemins.
