"Charming and with an excellent location," this "very nice, old-world hotel" opened in 1876 across from the Vienna State Opera and was once a meeting place for Austrian nobility."Exceptional accommodations" are decorated with antique furniture, original oil paintings, and silk wall coverings, while select suites on the top floors have private roof terraces. Updated rooms have iPod docking stations and flat-screen televisions. Dig into the Sacher torte, the chocolate cake that is a hallmark of the hotel, at Café Sacher, where the glassed-in terrace transforms into an open sidewalk café during the summer. Restaurant Rote Bar serves Viennese cuisine, including Wiener schnitzel, with Austrian wines.
