Heikel was a great host and provided us with good communication about public transportation. Heikel couldn't meet us when we checked-in, but his friend met us out front and let us into the apartment which was just fine. The apartment is located very close to underground and tram stops that provide easy access to downtown and areas of interest. The apartment was warm at night as it was summer in Vienna and the apartment is quite basic - minimal decor, etc. The apartment was great for us while we were in Vienna and was a perfect location for easy access to all points of interest. Thank you, Heikel!
