25 year old girl, student, looking for accommodation in Oslo

Hello, I'm Tiziana, from Italy and currently I'm studyng economy in Luxembourg. Next year I will have the pleasure to come to Oslo as Erasmus student at the "HIOA-Oslo metropolitan university". I will come with my friend Mandy, from Luxembourg,a new Erasmus student as well, and we are looking for an appartement with two single rooms or shared room, maybe not so far from our university. At this moment I'm living in Luxembourg in a shared flat with 5 other people and I'm  already used to the rules of coexistence and  respect of others. I'm a serious and trustworthy person with a great sense of duty and respect of others. I hope I will find as soon as possible an appartement  to share with a new nice people. Thank you for your help!
