For future guest: the airport information desk was not helpful. information desk staff doesn’t provide better transit directions which platform of the train station should be used. Same thing goes to airbnb home owner. When taking the train there are several platforms, we were lucky to find the right one. Ask the airbnb owner and airport information desk “which specific platform to use and specific train station name to get off”. Example the airbnb said “Patersten station”. but it was “Wein Patersten station”. The first word that you don’t know could be a different station. So make sure to ask for the correct station name. Uber is not reliable, we requested 3 uber’s but did not show up on the door we were told to wait for uber, that ended us being charged for €10 each time uber did not show up. We ended up using the train. Airport staff in Vienna are not as helpful.
