Looking for room as close as possible to the Metropolitan University Prague

I'm from the Azores, Portugal and I'm looking for a cheap room, since my scholarship is not  very high. I am calm, organized and can I can clean a house / room by myself without problems. Although I like to go out once in a while I'm more the type to stay at home and would prefer a room as close as possible to the Metropolitan University Prague were I'll be studying International Relations and European Studies. I'd rather not have to pay for public transports. I'll be staying for the whole 2013/2014 school year with no visits to my hometown.
