18 years old boy, search house near his university (Erasmus University)

Hello my name is Konstantinos, i am trying to find a room/apartment where will be near the Erasmus University (Kralingen), i have already 3 friends that stay in Kralingen so most of the time i will meet them after my study, i am a very friendly person, helpful and i can contact and chat with everyone, i want my roomates to be as tidy as possible and have some chillings in the rooms. I want to have night life but my goal is to be a mature student which will be very active. I play tennis and soccer and i hope to find a roomate that is keen on sports! Moreover, i hope to find a room as soon is possible because in some days tha university starts :). If you want more informations pmm.
