20 year old English girl, looking for accommodation in Milan

I am studying at universita degli studi dI Milano and so looking for short term accommodation (preferably in the centre), until the end of May, with the possibility to stay for June - August if I find a summer job. I am a  clean, friendly, relaxed, non smoker and am happy spending time at home but also sociable so will also go for dinner with friends. I am respectful and expect respect from my housemates aswell. I would love to stay somewhere where my friends from London could visit me occasionally at the weekends and feel comfortable too. I have previously lived in Santiago de Chile and am used to flat shares. I speak English, Spanish, Italian (and some French!) and am happy to share with people of any nationality. I look forward to hearing from you!
