22 year old girl looking for accommodation in Utrecht

Hello! My name is Patrícia Cunha and I am a 22yo Portuguese/Mozambican girl looking for a room in Utrecht from 26th of June to 30th of September. I'll be doing an internship through ERASMUS+ program near the central station and I am having a lot of difficulties finding a room with the budget that I have (max 350). I finnished my bacherlors in Nutrition last year at Coimbra Health School (Polytechnic Institute of Coimbra) and now I'm going to do a 3 months intenship trough my university. Please contact me if you have any doubt. This is my second (and last) ERASMUS, I did my first one last year, in Murcia-Spain. Thank you in advance.
