The apartment is very easy to find, and check in was a breeze. We stayed over Christmas 2019, and despite the expected low temperatures (and the fact that we'd just come from 40c in Sydney), the apartment was cozy & warm for the entire stay. The location is outstanding, it's across the road from a U-bahn station (don't worry, you can't hear it) and around the corner from a Tram stop. Both the tram and train are on very convenient lines, both will get you direct to many major attractions and very close to the city center. It's also a very short walk to two different supermarkets. We thoroughly enjoyed our stay, the location of the apartment made it extremely easy to discover the best of Vienna; the only criticism I have is that there wasn't any information provided about the property and being on a main road, there was some traffic noise in the mornings (to be expected in a big city).
