Everything went perfect - I was notified ahead of time on check-in / check- out situations. The location is phenomenal, 3 minute walk to Praterstern Bahnhof as well as Nestroyplatz taking you to the city center within minutes. I was there on a work trip but it definitely is a perfect place for a longer stay in Vienna. Sadly I didnt meet the hosts in person, but I may be in Vienna again soon 😉
