24 years old guy, erasmus student, looking for accommodation in Porto

I'm a calm person, looking for a single room well furnished, likely with a terrace. I've already lived outside from home and i like to keep the room clean and all the stuff ordered. I'm looking for roomates that enjoy company and are respectful of the others space,time but i like to have dinner together, i don't mind if they smoke, if they want to bring friends at home. I'm an open mind person and i'm looking forward to find an accomodation!
