I have only great things to say about my stay at Isabelle's. The apartment is tip top, and cozy, and the sofa/bed is really comfortable for sleeping. The location was perfect for me since I was attending an event in the area, but is not very far from the center of Vienna. Isabelle did a lot to make me feel welcome. Due to a planned weekend, she could not be present during my stay, but nevertheless she arranged things so that I could stay and get access to the apartment when I arrived. And she left me a nice welcome map with tips on restaurants in the area. Communications prior to my arrival were also very good and prompt. I can highly recommend!
