If you arrive by air to Vienna airport, we recommend that you take the regular light rail public transport, and save money on the expensive "CAT" CityAirportTrain. You can buy a ticket at the platform at the "ÖBB" ticket vending machines.
If your accommodation is located such that you will regularly need public transport, we recommend that you buy a 7-day ticket from Wiener Linien for EUR 17.10 (single tickets for individual journeys cost EUR 2.40). This ticket, or a weekly ticket, should also sell on vending machines - do make sure to select the correct starting date!
A 7 day ticket will also get you to our Donauinsel socialising location on the Friday, and it complements your airport ticket (i.e. you then only need to pay a smaller surcharge from the airport to the city border).
The best connected public transport stop near the University is "Schottentor".
Public transport information on google maps is fairly reliable. You can also download the app "WienMobil" or "OEBB Scotty", which have the most up to date information.
