Searching for a room in Zurich for 2 months

My name is Anastasiia (Nastia), I am an international student of the University of Freiburg (M.Sc. Neuroscience). I am coming to Zurich for my internship, which will last from 17th of October to ~middle or end of December. That`s why I am urgently searching for an affordable room.
I am 25, i`m open-minded and very andjustable, and would be happy to live with international or local people of any age. In my free time I would like to explore the city and go hiking, and sometimes rest at home with a glass of wine or beer :)
