Ilona was super nice, communication was very good and she welcomed us to the apartment and showed us everything we needed to know. She prepared a lot of leaflets for things to do in Vienna (even one in Japanese for my friend who stayed with me) and a list of recommended restaurants, cafes etc.
It's a typical old-style Viennese apartment with a very artistic and modern interior. The apartment was very clean and provided everything you will need for a short or longer stay. The bed was large and comfortable to sleep on. We were very happy with the apartment and recommend it to everyone!
