27 year old colombian girl, looking for accommodation

Hello! This is Ana, I'm a 27 year old colombian girl and I'll study a master course at the Politecnico di Milano. I'm looking for a single room for myself and another one for my friend Diego, who is also colombian and will study at Domus Academy. We would be really nice and clean flatmates :) I'll arrive next week but my friend is already there, so if it sounds like we are good flatmates for you please contact as asap :) We are looking to pay no more than 500 (including gas, internet, etc) and hopefully close to the citycenter. 

Thanks!
