There are plenty of hotels in Vienna which have a good public transport connection to the conference venue. Please use Google Maps to look for hotels near the conference venue or use the booking platform of your choice.

We suggest that you choose a hotel near to a station of the underground line U3 because this line offers a direct connection to the bus to Otto-Wagner-Arael (48A). Both underground and bus lines are running at dense intervals (5 to 8 minutes) all day long.
