You get out of the taxi. In front of you is the listed Palais, once designed by the famous Viennese architect Theophil Edvard Hansen and part of Vienna's famous Ringstrasse. Admittedly, anyone booking into a hotel run by Europe's oldest luxury hotel group has high expectations. But the Palais Hansen Kempinski Vienna not only meets them, it exceeds them. The building was built as a hotel on the occasion of the 1873 World's Fair, but was never used as such. Since 2013, the jewel in the first district has finally lived up to its purpose as a luxury hotel and proudly bears the name of its architect, who incidentally also designed the parliament, the former stock exchange and the Musikverein building, among others.
