Practical Information


We recommended to book a hotel soon. One option is Hotel B&B, who offer free cancellation until the day of arrival. The hotel is located one subway stop (or a 20 min walk) from the central railway station Bonn Hbf and 1.8 km (a 20 min walk) from the meeting site. Contact Andreas Weber for other hotel options near the city center.

Getting to the Meeting Site

Meet us in the lobby of B&B on Wednesday at 9:15 for walking to the meeting site together.

For going on your own, enlarge the map below. The marker "Informatik-Zentrum" is exactly where to go. From Endenicher Allee walk around "Campo Mensa."


By Plane

Fly into Frankfurt (FRA). Then take a fast train (ICE, 37 min) from the railway station Frankfurt (Flughafen) Fernbahnhof inside the airport to Siegburg/Bonn. Find connections and buy tickets online at A "Flexpreis ticket" allows you to use any train on a certain day.

From Siegburg/Bonn take Tram 66 to Bonn Hbf (24 min). Then take a subway in direction Bonn West, which is the next stop.

Caveat: Do not fly into Frankfurt Hahn (HHN).

By Train

Take a train to Bonn Hbf. Find connections and buy tickets online at Then take a subway in direction Bonn West, which is the next stop. At Bonn West walk the street in the direction of your train (2 min). B&B will be on the left.
