I had a great time at Eva & Michy's place. The location of the apartment is perfect, especially if you are in Vienna as a tourist. We haven't used public transportation at all, despite the fact that I brought my parents who are in their seventies and we had a rather ambitious agenda for our stay. All major attractions and must-see places in the center are within walking distance. Location is indeed unbelievable. The place is spotless and well equipped and the apartment is spacious and great. It is a pleasure being there at night after a long day of sightseeing. They are great as hosts and are discreetly present when you need them, without being intrusive at all. I can only recommend their place and I don't doubt that you can have a great time there.
