From the airport to the Baronesse.

You can either take the bus 'Vienna Airport Lines' until you get to the Westbahnhof. Opposite the station there is a stop for public transport, behind which you can take tram nr. 5 to the Praterstern. Please get out at Lange Gasse. Diagonally opposite you will see the Baronesse.

Or with the fast train/Schnellbahn (station directly in the airport) , the S7 will take you to the station Praterstern Wien Nord. Please leave the station and take the tram nr. 5, direction Westbahnhof. Please get out at the station Lange Gasse and cross the main road (Alser Strasse). The Baronesse is a few steps from the crossing.
