My partner and I really enjoyed our stay at Cristina's place, and would recommend it to others. It is a five minute walk from Nestroyplatz on Line 1, which can take you close to the nightlife near Schedenplatz (one stop away), and the night market and shopping near Karlsplatz (three stops away). The apartment is very clean and simply furnished. We were quite comfortable, and enjoyed the complimentary tea and slippers at the end of a cold day spent out walking.
