The location of this apartment was amazing! We walked to many of our attractions and this apartment was very close to many sites and the train station. As far as airbnbs go, our bar is not very high; however, we do expect that the apartment is clean. This airbnb was not cleaned before we arrived. The towels were stained (most likely dirty), the bathroom was not cleaned, trash was left over from the previous guests, and dishes were left in the drying rack.
Although we don't hold this against the host, there was street construction going all night long, and the floor below the apartment had construction starting in the very early hours of the morning. Luckily for us, we only used the airbnb to sleep and to shower before exploring Vienna.
