Excellent and well equiped apartment next to the central train station in Vienna. 15/20min walk to the Opera and only 2 metro stops from the city center. Easy access with the nuki app (just make sure your phone has battery). Very convenient apartment to travel with kids (kid's tub and crib available). Despite the location the apartment is very silent. Everything is as it looks in the pictures. Andreas is easily reachable and always replied within minutes.
