Great place for 4 people or a family. Very good location, metro, tram and bus lines very near, but we also walked to the city centre down Mariahilfer strasse a couple of times.
The apartment itself has all necessities, and much more. I can't think of one thing we lacked.
Kalouda, the host, is very welcoming and helpful, excellent and fast communication.
I would deffinitely stay here again.
