21 years old engineering student girl looking for accommodation in Porto

I am a 21 years old Electronical engineering student girl from Latvia, who is going to do an Erasmus for one semester in Instituto Superior de Engenharia do Porto. Looking for accommodation and roomate/-s for shared flat, room or dorm near the university or in city centre. I study in my third course of engineering, so I will not be a loud roomate, but will help you with higher math problems or any problems, because I try to be kind (: This is not my self-advertisment, just saying :D
