21 year old girl looking for accomodation in Oporto

Hello! Me and my friend Sandra will be doing an Erasmus exchange from February to June in Oporto. We are looking for a apartment close to the center and shared with other students. We prefer to share apartment but we have also considered living in separate apartments. Sandra and I both are coursing our third year of a degree in Marketing, Adverstising and Public Relations. Barcelona born and raised. Oporto seems like a great city and all we need is a nice apartment to stay at that is close to the city center and to neighborhoods with a good student vibe.
