We had a great experience staying at Caroline's apartment in Vienna. The location is perfect - it's right in the center of the historic part of the city and most of the popular sights are within short walking distance. Caroline personally met us on arrival and gave us a warm welcome and good introduction to the place. The apartment itself is very clean and bright. It's located on the 6th floor and features spectacular views from the window. The couch was also very comfortable to sleep on. We would definitely recommend staying here to a friend.
