Room in Groningen, preferably city center

Hi, my name is Emily and I am from the United Kingdom. I am currently studying my Masters in International Communication at Vilnius, Lithuania and will be coming to Groningen from the 18th January 2014. I am in desperate need of a room as stupidly I have left it a month before I go to start searching! I am easy to get along with and have been told I am quite funny! I do not really know what to write about myself without sounding like a complete idiot- if I do not already! Basically I am a very happy person and make friends with nearly anyone. In regard to my ideal flatmates, I have no prefence over gender but it would be nice if you are sociable and see the bright side of life- cheesy I know so I apologise! Also it would be excellent if the room is in Groningen city center, but I am happy to consider anywhere in the area! 600euros is the maximum I want to pay per month but that would have to include bills, and obviously the cheaper the better!
