Thanks to self check in and we never had any problems at all . We arrived around 3AM due to unforeseen reasons (7hours delay from flight) . Victor's instruction is clear and very informative . The house is very easy to find , super clean and spaceous . Perfect for a family/group of 4 or even 5 on a budget . Minimalist design which i totally liked and we basicly had all things we needed . We had an awesome stay in Vienna and the flat has an easy access to public transportation like trams , buses and subway . The place is so quiet and peaceful . So even if its a bit far from the center (but it is close to Schönbrunn Palace) , Johnstraße subway station (about 3minutes walk from the flat) is just few stops from Stephanplatz (orange line) and connections to railway train station , going back to the airport has never been a problem for us (we left around 4:30 AM) . The apartment is highly recommended !
