My family and I had a great stay in Vienna at Oscar's Apartment. The apartment sleeps 5 people comfortably. It is short walk to the U-Bahn at Karlsplatz. It is 1 block from the Ringstraße and within walking distance of the Opera, Albertina Museum, Haus Der Musik, and Kärntnerstraße. We even walked to Stephansplatz from the apartment. It is ideally located for a trip to Vienna.
