We have stayed many time in Vienna and this was one of our favorite places so far. The apartment was spacious, comfortable, and very nicely decorated. We found it to be extremely quiet. The huge terrace was a big plus. The kitchen was well stocked and even had a small Nespresso machine (for pre-coffee before heading out to a cafe 😊). There are several food stores a short walk or one tram stop away. The little square in front of the building is a convergence point for three tram lines so it is super easy to get wherever you want to go. Communication and check in/out was great. We would definitely return.
