Corinna's apartment is perfect for visiting Vienna. In the pictures it seems smaller than it really is. We were 4 adults and we were very comfortable there. The only really small thing is the bathroom sink. The mattresses are very comfortable and the place is very clean. The apartment is very quiet and at the same time it is next to the center (and very well connected with everything, as there are trams, buses and metro 3 minutes walk from the house); next to the most touristic places, but in a neighborhood with a strong Viennese character, in which one feels an inhabitant rather than a tourist. The location is unbeatable! Corinna is a very nice person, close, flexible and it is worth following her advice on what to do in her city. Her "Vienna guide" was a fantastic welcome! It is also very easy to communicate with her. When we return to Vienna, we will definitely return to Corinna's apartment :)
