The descriptive tag of “casual luxury” is spot-on for this design hotel. Warm and inviting contemporary rooms are housed behind the historic facade of a 19th-century building with views of the Ringstraße and State Opera House. Modern meets traditional in the Ring Suite, with contemporary furniture and floor-to-ceiling windows. Unlike many of its upscale hotel neighbors, there aren’t any nods to the Habsburgs or Vienna’s imperial past. (Sorry, no gold faucets or garish decor here!) The hotel has already become a favorite spot for members of the music and movie world, with a guestbook boasting visits from the likes of Scarlett Johansson, Axl Rose, Beyoncé, and Morrissey.
