Schottenfeldgasse 60 Vienna
From the Airport (Schwechat), the CAT train departs every 15 - 30 min and arrives at Wien Mitte Landstrasse. Take the underground line U3 in direction Ottakring and drop off at Westbanhof.
Switch to the U6 in direction Florisdorf and drop off at Burggasse/Stadthalle. That's the studio Underground station.
Once you get to the arrivals hall with the big sliding doors left behind you, walk 30m on the left side of the big hall, and on the right hand you'll see a couple of desks of Taxi companies. 40100 is one of the most reliable. It's usually 36 € for one person to the city, and there are deals for more people (e.g. 43 € in total). Check the Taxi site here, it's in german but pretty easy to figure out. You can also call, everyone speaks english.
The Studio Address is Schottenfeldgasse 60, 1070 Vienna
