Wanted: an apartment near city centre/faculty of social sciences

Hi! I'm Sara, a 21 years old girl from Finland, and I'm looking for a place to stay during my exchange studies (from september till february). I would like to find a single room, but it would be awesome to share some bigger apartment with other exchange students! I'm going to study at the faculty of social sciences, so apartment should be located near the city centre. I'm looking forward to find roommates who would like to hang out, travel and have fun with me!
