Veronika's apartment is cozy, nice and clean! It's at walking distance from the city centre and close to the metro line U2 and the tram line n.2. Also, if you plan to reach Vienna by car, there is a very cheap parking at just 500m from the apartment (5€ for 24 hours). Communication was very good throughout the reservation and check-in phases 😀
I definitely recommend Veronika as a host (and Vienna as a destination, of course!) 😉
