22 year old student, looking for flatmates/accommodation in Milan

Hi I'm an Spanish Engineering student and I'll be studying at Polimi for my Erasmus starting in september 2019. I am looking for any kind of accommodation actually, a university dorm or a shared flat would be the best option. I will be studying at Bovisa, but actually anything within 45 minutes from there would be fine I guess. 

I am used to sharing a flat and I have also lived in a dorm so I'm quite fine with both options, however I am open to any kind of accommodation. I am quite open and sociable, so it won't be a problem getting along with me.

I speak Spanish, English and German in case it matters, also a bit of Italian.
