Our stay at Estrella's and Gerald's place was enjoyable and smooth!
The check-in was super easy and flexible, the place looked exactly like the pictures, was very cozy, and had a nice authentic Viennese flair (herringbone parquet, high ceilings).
The area was very nice as well - close to the Landstraße/Wien Mitte station, which is very convenient when coming from the airport, and still, very central Vienna so that one can easily walk to the first district.
Overall, we enjoyed our stay a lot and can highly recommend the place!
