Sans Souci might translate to 'without a care', but the interiors of this new Viennese property have been put together very precisely indeed. A former inn dating from 1872, the grand building in the central bohemian quarter of Spittelberg, has now received a vigorous makeover by Philippe Starck and John Hitchcox's London-based Yoo Studio. On the outside, deep purple window coverings against the building's classic white façade have an instant and dramatic impact, while the interior is a sumptuous mix of modernist and antique furniture. The 63-room lodging's standout feature is a vast collection of modern art, including original paintings by Roy Lichtenstein and Steve Kaufman, while an eclectic assortment of chandeliers grace almost all the public spaces, including the indoor swimming pool in which guests can unwind after a day of culture at the nearby MuseumsQuartier.
