We stayed in Conny and Peter's apartment for two nights and really enjoyed our stay. Although we did not spend much time in the apartment, we found it extremely clean and both Conny and Peter were very hospitable. The private room was a nice accommodation and it was decorated with things to do in Vienna and suggestions for where to eat (multiple of which we used). We certainly didn't have a problem with any of the house rules, but be sure to note them before booking. We would stay again!
