28 years old girl is looking for accomodation in Zurich, near Botanical Garden due to a internship in University of Zurich

I am a Ph student in Biotechnology at the University of São Paulo, USP, Brazil. I am 28, female and single. Between 23th to 27th February I am going to Switzerland to do an internship at the University of Zurich. I'll stay there for about 3-4 months. My internship not it will be especifically in University of Zurich, but it will be in the Department of Botany (Botanical Garden), located at Zollikerstrasse 107 8008 Zürich. I would like to live near there in this period. I am looking for a room with shower/WC (preferably), but if not, not a problem, with internet connection, during the period mentioned from February until June.

Thanks
