The apartment is just as announced. Small but enough for a short stay. Everything was clean and working, and the host was kind enough to leave a map of Vienna and give us local tips. The apartment is also close to a restaurant that serves typical Wiener food for those who are interested in that.
Some tips: the apartment is very near Westbanhof station, which is NOT Vienna’s central/main station. You’ll need to get the subway after arriving in Hauptbahnhof.
Also, future travelers should be careful to write the address carefully on Uber or any other app as there is another street similar in name in another neighborhood. So, heads up! We got lost!
