Stefan was a good host. He was at the apartment at the time we agreed upon. The apartment is very well located (just 5 minutes to the Parliament) and we were able to walk to many of the major attractions in less than 15 minutes. Access to public transport is very conveniently located. Tram/Strassenbahn stop is about 50 m away, and the tram connects to the U-bahn/train station.
It is also extremely well appointed, clean, well decorated and comfortable and is absolutely wonderful. It is so nice and quiet too. The apartment is exactly like it appears in the photos, great space, very big rooms. We would definitely recommend this apartment to others visiting Wien.
