A quirky but relentlessly upscale and obsessively design-conscious venue was created when the high-end caterer DO & CO took over four floors of the Haas Haus. Some find it pretentious and others love it, but you can't beat the location. From Stephansplatz smack in the middle of the 1st district, guests take an elevator from an impersonal ground-floor entry up to the check-in on level six, somewhat awkwardly positioned within a busy area that otherwise functions as a vestibule for the stylish Onyx Bar. The rooms are artfully minimalist and very comfortable, with yummy but hard-to-define tones of toffee and putty. Sybaritic details include in-room clear glass showers. Bedrooms have mahogany, louvered doors, lots of polished travertine, dark-grained hardwoods, and floor plans that follow the curved walls and tucked-away balconies of the Haas Haus. Views encompass the crowds scurrying around the all-pedestrian Graben and Stephansplatz.
