Planning where to stay in Milano

Rotterdam is getting prettier every day, I know is the sun, the cloudiness and greyness of six months have given space to a "blooming" city. In less than three months I will be living in Milano and preparation has already started, at least in my mind... looking for a place.... what websites to look?... is anybody that I know living in Milano? And of course the usual confusion, three rooms actually means two and a living-room. Ah and I still have to figure out what a Libero 4+4 contract is :s
