we were there only one night because we had an early flight.
to be honest a perfect location for us! not far to S-Bahn which can bring you to the airport, we took cab tough (also very easy) taxi waiting place right in the front of the apartment entrance!
if you like photography like i do (iam photographer) the balcony is great place to make night photo (long exposure photo) of Amusement Park of Vienna (Giant ferris wheel)
