It was a wonderful apartment, extremely clean, very spacious and cozy. The area in which is situated the apartment is very peaceful and close of one of the main underground station. Rainer was also extremely nice to us and very comprehensive for the last minute changes of flights/schedules. Of course Vienna is magnificent, but Rainer also had many documents available for us with suggestions of place to go. The free bottle of wine was also a very nice surprise! I will clearly take this apartment again when I come back to Vienna one of these days.
