Paola's apartment is a good option for people on a budget in Vienna. Consider that the apartment is old, but in very good conditions. It has everything you need for your stay and it was tidy and clean as expected. Location is good and it is connected to the city by tram and metro near the apartment.
It was a little noisy at night. Neighbours were having fun until 1am every night. So if you prefer a quiet place this might not be the place for you.
