Hi,
I would recommend the Damage Town (
http://www.damage-town.com) at Mariahilfer Strasse 23-25 (Doorway at Theobaldgasse 20)/Subway Line U3 Station Neubaugasse (
http://www.wien.gv.at/stadtplan/spread. ... 102ee80bc0) and the Spielerei (
www.spielerei.at) at Mariahilfer Strasse 88a/Subway Line U3 Station U3 Zieglergasse (
http://www.wien.gv.at/stadtplan/spread. ... 3fc0af8bc5).
The are both at Mariahilfer Strasse, which is a long shopping street, and you can walk from one shop to the other.
From Vienna International Airport you either take the City Airport Train (
http://www.cityairporttrain.com/content/fahrplan.php) or the S7 to Landstrasse/Wien Mitte. They both take the same route, the CAT is faster and more expensive, S7 is slower but much cheaper. At Landstrasse/Wien Mitte (don't be shocked, this station is quite old and ugly) you enter U3 with the direction Ottakring, which takes you directly to the Stations mentioned above.
Here is some additional information for the Public Transport:
http://progs.wiennet.at/addedvalue/f400 ... 21&HID=4804-5 hours isn't a lot of time, but you could take a quick stop at U3 Station Stephansplatz and visit the Stephansdom (
http://en.wikipedia.org/wiki/Stephansdom) (
http://www.wien.gv.at/stadtplan/spread. ... f062fc7012) and the streets around it. At Zanoni & Zanoni at the Lugeck northeast of the Stephansdom you can get some good ice cream - for all the other beautiful places in Vienna, like Ring Strasse (
http://en.wikipedia.org/wiki/Ringstra%C3%9Fe), you should visit Vienna a second time.

Have a lot of fun!
