Imperium Residence is the most exquisite and luxurious place to stay in the heart of Vienna! We wanted to be close to the Opera and Stephansdom and it is literally 5 min walk away from either landmark. The building was the most beautiful architecture and the design of the apartment was as you were in one of the palaces around Vienna. We considered staying at the Bristol or the Sacher Hotel to have a true Viennese experience in this historic city but realized the Imperium Residence is much better choice and the most authentic place in the city. The apartment and service were both impeccable - from the airport pick up service to the impressive tray of fruits and pastries awaiting in the dining room. We were celebrating my mother's 70th Birthday and after just mentioning our special occasion to the wonderful concierge, the Imperium Residence team surprised us with a generous gift, cake and champagne for my mother's birthday, making her milestone unforgettable. No other place would have had such personal touch and special attention! We highly recommend the Imperium Residence to anyone visiting the city and wishes for a luxurious and authentic experience in Vienna! We travel the world and enjoy hotels like the Ritz and the Four Seasons and this was hands down the best place we've ever stayed at! Thank you so much to the Imperium Residence team for such wonderful stay!
