This iconic hotel has taken centre stage in Portorož since it first opened in 1910 during the waning years of the Habsburg Empire. Combining Viennese elegance, modern design and of course the famous Kempinski flair for style and service, the hotel is quite simply one of the grandest places to stay in all of Slovenia. If price is no object, book one of the two Laguna suites, which include a rooftop terrace with a private Jacuzzi and breathtaking views of the Adriatic Sea.
