We stayed at Oscar's Gusshausstrasse apartment for 5 weeks from mid-September to October 20. This was our fifth and VERY BEST Airbnb rental. The location could not have been better and the apartment is attractive, spacious and remarkably comfortable.

LOCATION: We are a couple in their 70s who still walk but not as briskly as we once did. Still, by our leisurely pace, there is a fine grocery store only a 5-minute walk away, plus a larger grocery, restaurants, pharmacy and dry cleaner all within a 10-minute walk. We visited Vienna partly for the music and found we could easily walk in 8 minutes to the Konzerthaus and to the Musikverein (home of the Vienna Symphony), and via the Karlsplatz underpass could walk to the State Opera in 12 minutes.

The apartment is barely 3 minutes from Karlskirche, and 5 additional minutes walking across Resselpark and Karlsplatz brings one to a wonderful feature: the underground passage in which one can catch 3 of the 6 U Bahn subway trains, most of which arrive within 3 minutes. We suggest disregarding earlier negative reviews about this passage because it has been totally renovated, is now lovely, and regardless of street-level weather or traffic up above can lead one underground to several useful exits within the busy central city area (such as the Opera). Once we got our bearings we used that passage daily to walk to museums, churches and most everything else we wanted to see.

THE APARTMENT: Oscar's apartment was remodeled and imaginatively decorated by Bo, his architect mother. She lived nearby and Oscar's lovely sister Vicky lives right next door. Although the Airbnb photos were perfectly accurate, we were delighted to find that the apartment was even MORE spacious and MORE comfortable than it appeared to be in those pictures.

The two primary beds are great: in size, both are 3 inches wider than an American "Queen" bed. The loft bed is in a large, well-fitted closet/dressing room adjacent to the second bedroom; the master bedroom has its own large, well-fitted closet/dressing room. Except for ample spare linens, both closets were empty, with plenty of hangers.

The neighborhood is quiet and the new double windows kept out any street noise. The radiator heating system worked beautifully, and the greatest surprise when October arrived was to discover that the marble bathroom floor was heated -- as was the towel bar. The Miele washer and dryer worked beautifully.

STAIRS: This apartment is not for those with serious knee problems. This wonderful old building has very tall ceilings, meaning that there are 40 steps between the street and the apartment. But they gave us no trouble.
