We did not get to meet Anja upon arrival, and was shown in to the apartment by a friend of hers, who was not very knowledgeable about the apartment itself, which key was for which door, etc.

At first, the layout is a bit confusing about where Anja's space ends and yours begins, but it worked out just fine. The apartment is in a great location in a popular shopping district with tons of restaurants, etc around. We had everything we needed in the apartment and enjoyed our stay in Vienna!
