This is an excellent place to stay in Vienna. It's located in a quiet and safe neighbourhood and yet with excellent connections to the city center, either by bus 10A/39A and U4 (20 minutes to Schwedenplatz) or Strassenbahn 37/38 to Schottenring (15 minutes).
Also close to many academic centers and thus ideal for staying when working there.
I will come back next time.
