It was very nice of the hosts' dad to allow for a late check in around midnight. The apartment is very spacious and has everything one might need. Internet worked very well. It's not a very warm apartment, but there's an electric heater in the bedroom, which was more than enough to compensate. The street is quite crowded, so it might take some time to find a place for a car. Shoenbrunn palace is easily accessible by tram. Overall it was a very good experience.
