20 year old French Med student looking for accommodation in Gdansk-Sopot-Gdynia

My name is Elisa, I'm looking for a room in a shared flat or house, or a room in a dormitory. I'm a French Med student and I'm coming for a year with the Erasmus Programme. I don't want to live alone, I'd like to live with other students, Polish or Erasmus, so that I can improve my English and meet new people. I'm friendly and talkative, though I'm a serious student and I will need to study a lot so I need a desk in my room. I'd also like a "real" bed, I don't like sleeping on a sofa or a couch. Ideally, I'd like to live near the Medical university of Gdansk, but I'm also interested in living in Sopot. I also think that Wrzeszcz is beautiful so I would also love living there. I'd like to be alone in my bedroom but for me, the best place to live is a flat with 3 to 5 or 6 bedrooms with other students in each bedroom. I'd really like to make this dream come true ! I'm sure I will find something perfect.

I can't wait for your answer !
