A great university if you want to meet international students, appreciate unique architecture and rich history (the university was founded 1365 and is the oldest in the german-speaking world) and, of course, if you speak fluent german, although during your studies there could be some lectures or seminars in English. There are many libraries in all the faculties (which are by the way spread out in the best districts in the city). And despite the huge amount of students at the university, making friends has never been easier for me. And also come on, Vienna’s the best.
