I really recommend this place! This is one of the best Airbnbs where I have stayed. It's extremely clean, spacious, and confortable, it has everything you might need, from well-equipped kitchen and bathroom to a computer and printer and even blackout curtains in the bedroom, and it is right next to a tram station with direct trams to the center and the main train station. The host was incredibly helpful: he gave me lots of tips about Vienna, including a detailed description of how to get from the train station where I arrived to the apartment, and when I checked in, even though it was already late at night, he took the time to explain to me the public transit system and show me points of interest in the map, and he even helped me buy a ticket for the train to the airport (without his help I would have payed much more than I was supposed to).
