Christiana's place made all the difference in my stay in Vienna. It's tucked away in such a quiet garden that you forget a tram stop is just outside the building door. Also, Mariahilfestrasse, the Museumquartier and Westbahnhof are all a short walk away.
I haven't met Christiana but she made sure the flat had everything I needed and would email every now then to see if I needed anything. A truly classy landlady. A heartfelt thank you, Christiana! :)
