Italian student girl, looking for a room in Madrid

I'm going to study at the UCM so it would be great a room near the University. I'm looking for a room where i can relac but i would love to have roommates my age that are interested in social activities with me. I'd like to find a place where I feel at home and also to find friends. I like to spend time in the city and find the local treasures. I study Contemporary Art so I like to go to the museums and galleries. I already lived abroad for two years so this is gonna be my third one. I'd love fo find a place where i can stay in the common areas to chat and spend time with the other roommates and maybe study together. I'd like to have some Spanish friends so they can show me the city and the best spots that a tourist doesn't know.
