If you have business at Vienna International Centre this is a great spot. Very close to the U bahn stop, walking distance to VIC. Not much to do though. Also the area is multi level and full of highway and rail so your GPS is going to make finding the place a challenge. Its a 33 story modern tower.
I would have liked better eating options in the area and at the building itself. But there is a gym on site. Thats nice.
