I stayed for almost three weeks in November, visiting the Univesity of Vienna. Very nice, roomy, recently renovated apartment. Centrally located and quiet at the same time. The apartment has three large windows towards a large interior courtyard and plenty of sunlight. Great workspace, well-equipped kitchen, comfortable couch. Easy access to grocery shopping. The location is a short walk to the University of Vienna, so perfect for a visiting academic. Internet was fast and reliable. Several great restaurants and key museums are within walking distance. Don't miss the Volkskundemuseum (Museum of Folk Life and Folk Art), which is around the corner from the apartment.
