Vienna or Wien in german is the capital of the Republic of Austria. It is by far the largest city in Austria, as well as its cultural, economic, and political centre. As the former home of the Habsburg court and its various empires, the city still has the trappings of the imperial capital it once was, and the historic city centre is inscribed on the UNESCO World Heritage List.

Common points of reference are often used in Vienna in addition to districts, most noteablly public transportation stops. Reference to U1/U4 Schwedenplatz or Schwedenplatz (U1, U4) means that something is near to the Schwedenplatz stop on the underground lines 1 and 4. Normally if the place is not directly at the subway stop you can ask around and find it easily.
The Vienna Tourist Board web operates information and booking booths at the airport Arrival Hall, 7AM-11PM and in the center at 1., Albertinaplatz/Maysedergasse. Information and free maps are also availible from the ÖBB InfoPoints and offices at train stations.
