Great location, easy walk to Stephansplatz and around Vienna. Very close to a u-bahn station. Anna and Vladan are very quick to respond to any queries. Our train was delayed coming into Vienna. We messaged them, and within a few minutes they had reassured us that they would be able to meet us at a later time. We had a little washing machine problem, and they responded very quickly and came over to help us out. Overall a great apartment and visit to Vienna!
