looking for a student room/studio in the hague (long stay) with registration

Hi guys! My name is Francesca, I am 20 years old and I come from Italy. I am going to start my bachelor of International Relations and Organisations at the Hague campus of the Leiden University in September and I am looking for a room (which I could take also from July). I can't wait to start my experience at university and I am looking for a place where I can have my own space but at also enjoy my time with roommates. (Please keep in mind that I don't speak Dutch, but my english is really good)

I am looking either for a single/shared room in a shared apartment or student housing and my budget goes from 300€ to 425€ incl. or for a studio (I'd like to have my own studio but some common rooms to share with the other students) and my budget in this case goes to 600€ incl.

About myself, I am a very open-minded, friendly, dynamic, easy-going and indipendent person. I like doing a lot of things, but above all sports. I practise athletics since I was in middle school and I'd like to continue in the Netherlands.
