25-year old student looking for an accommodation in shared flats

Hello, my name is Hannes and I'm looking for an accommodation in the center of Porto or roommates who either can offer a flat or trying to find one as well. I come from Germany, studying Literature sciences there in a University-town called Jena (middle Germany). I just arrived in Porto and I'm looking forward to study abroad, but indeed I'd like to find a suitable accommodation as soon as possible. If you're interested let me know, looking forward to hear from you.
