19 yr British student looking for accommodation Sept-July

Hi, I'm Jai, a nineteen-year-old first-year student from London currently studying for a BA in literature at the University of Warwick in Coventry. I will be doing a year abroad as part of my participation in the Erasmus scheme for the academic year 2017-2018 and will need accommodation from mid-September to early July at the earliest. It would be great to share this experience in Pisa with one other student or a group. 

I am preferably looking for a shared apartment with my own room. Apart from this, I am used to sharing with others so I have no issues with sharing bathroom facilities and kitchen/dining room areas, as long as the person/people I stay with are considerate with chores, as I will also be.

I'm not picky in terms of flatmates- gender and nationality do not matter, but it would be great to find people between the ages of 18 and 21. I am quite social myself and enjoy going out but I am very respectful to those who do not, so this would not be an issue to people who prefer to remain at home to wind down. I'm also very much a night owl so I often work late at night, however, again this would not be problematic for people who aren't as, again, I am used to working in silence from living in student accommodation for my first year.
