The apartment is pretty close to Pratestern Station, around 8-10 minutes walk (if you take the exit to Heinestraße/Praterstraße). The check-in went smoothly and the size of the apartment was perfect for two people. The responses from Stjepan&Dajana were very fast and they were extremely helpful on explaining which train to take to go to the apartment from Vienna Airport. Despite being very close to Tram stop (Tram line 5), the apartment was surprisingly quiet and calm. Definitely a really good place to stay for a short vacation!
