Great appartment, seem to be all new. Fantasic balcony and as we were in the 6th floor, totally quiet. Make sure you park your car in one of the official parkings around the corner. They are 24/7 open and the cost is 3.70 EUR/hr.
Whilst the location is perfectly suited to explore Vienna, there are some street bars nearby the entrance and slingle ladies may get intimidated passing by.
