Vienna’s unique boutique hotel. Within easy walking distance of Vienna’s historic city centre is this charming boutique hotel. But it comes with a twist. Established in 1901, the Hotel Donauwalzer is renowned for its friendly and helpful service, and for its unique, classically Viennese entertainment options. At the breakfast buffet, indulge in some sparkling wine. On Sundays, sit back and enjoy live music. And on Saturdays, opt to take part in the private waltz course.
