looking for accommodation in rome

I am looking for a room (preferably single-bed but worthy options in a shared-room would also be considered) in Rome starting from late September/October till February. Would take a look at any variant near the A metro line stations. I'm going to Tor Vergata university, so something in between the city centre and the uni area would be awesome! If you/your friends/mates/relatives have an apartment to rent or if you've already found the apartment but still looking for someone to share it with, just let me know. Would highly appreciate! Anyone? Anything?
