My husband and I believe this is the best option in Vienna for an extended stay (we stayed 17 days). It is positioned at the center of Vienna, at Karl Platz, near the Opera, Kartner, and Grober Strasse; I could not imagine a better hotel location. The hotel personnel was amiable and helpful at each instance of our stay. We stayed in an elegant executive apartment on the 3rd floor that was very spacious, clean, tasteful, and comfortably furnished. We had everything needed for a more extended stay (spacious closets, comfortable beds, a sofa, an oversized bathroom, handy kitchen). The (free) coffee and water corner at the ground level was our highlight of each day of the stay. We strongly recommend the Living Hotel An Der Oper to everybody who comes to enjoy Vienna.
