24 years old girl look for a nice and quiet apartment in Vienna

Hello everyone! I'm 24 years old student in Rome and I'm looking for a well-kept and welcoming accommodation where I can feel calm and "at home" during my first experience of living abroad thanks to the Erasmus traineeship. In fact, I will be doing an internship in a Viennese company from March to June.
I would like to be able to meet girls of my own age with whom I can make friends, share my experience, my house, chat during meals, who I can chat and get around the city.
