24 y.o. girl looking for an accommodation at Porto

I'm Claudia, a 24-year-old girl. This year I decided to continue my studies at a University of Portugal, more precisely at the University of Porto. Until then, he was studying for a degree in Chemical Engineering at Universidade Federal Fluminense, which is located in the state of Rio de Janeiro. However, because I was very interested in the Environment and Energy part, I decided to change the focus of my degree and chose the Environmental and Energy Engineering course at FEUP. I'm looking for a roommate who is organized, who knows how to share a space in common. I would prefer a non-smoker (I have a cigarette allergy) just as I prefer a girl as a roommate. Age for me is not very important. I hope I can make this experience a good thing for both parties and that we can be friends.
