Girl looking for one single room in Pisa

I am a Erasmus Mundus student looking for a single room in Pisa for the spring semester. I am studying conservation science and will be in the Chemistry department for my final thesis. Before coming here, I have been studying in Portugal, Greece and now in Rome, so I know how to live with other people. I am very clean, quite and well-behaviored girl but also flexible. I hope to find a shared apartment with proper kichten, bathroom and internet. I want to walk to university, so I hope the place is not too far from center. Thanks:)
