After multiple trips to Vienna, the latest one in which we stayed at one of Justina's places was by far the best in terms of accommodation. We had absolutely no trouble finding the place, as the Airbnb listing is accurate and the host provided exact guiding information with useful cues. The place is very stylish, not only the apartment but the building also has art installations and a really good vibe to it. All the amenities were working as presented on airbnb, cooking and cleaning essentials were present, heating was working nice and everything was really clean. The instructions sheet you'll find inside solves your problems regarding garbage disposal, wifi, etc. There are also local dining and grocery shopping recommendations provided.
The place is right in the heart of Vienna, and if you're into that you can walk to everything of interest, or maybe take a train from the Mitte station which is just a 10 minutes walk down the block of maybe rent a car / bike / scooter as there's the allowed zone for parking /taking all of these by app in the vicinity.
We'll surely come back to this place or another one of Justina' when coming to Vienna again.
