We had a great stay in Caroline’s Airbnb. The flat was stylish and beautifully decorated in a traditional Viennese building with a high ceiling (which I love!). The location was great - only 3 minutes walk to a tram station (in front of a park with Schloss Belvedere) and from there a tram goes directly to the 1st district. The neighbourhood was quiet and we had no trouble catching a good night sleep. Communication with Paul, Caroline’s co-host was very smooth and he was very understanding of our situation as we had to arrive later than we agreed.
Overall, this place is highly recommended if you are planning to visit Vienna!
