For a truly unique experience I would highly recommend booking this fantastic accommodation. You can't get a better location and the property itself is a gem at the very heart of Vienna. All of the rooms are dedicated to one of the historical royal figures including Sisi and Franz Joseph. The attention to detail is superb and you can enjoy the privacy of your own apartment while benefiting from services one would usually expect at 5* hotels, e.g. a full breakfast buffet prepared upon request, daily turndown service, fully stacked minibar (whereas the word 'mini' does not do justice to the actual selection of both alcoholic as well as non-alcoholic beverages). The communication with the host was very welcoming and already pre-trip we were provided with all the necessary as well as additional information about the city and the flat's surroundings which made our stay even more enjoyable. If you want a royal experience this is the place to stay. We will definitely come back!
