This classic apartment with high ceilings and tall windows is very quiet and wonderfully located in a quiet neighborhood near the Naschmarkt and close to the Karlsplatz U-Bahn station, which meant connections were easy to the Vienna airport or to the Hauptbahnhof. There are good restaurants in the immediate area separate from the crowds at the Naschmarkt, but we enjoyed both, a lot. And it was a moderate walk to the Opera and Innerstadt. It is up several flights of stairs but there is a small lift if needed. There is no AC but there were several fans and plenty of windows so we were comfortable during a warm week (85F). Check-in and check-out were quick, efficient, and friendly. We will definitely stay here again.
