33 Year mature and decent internee at Maastricht, looking for shared room for 2 months

Hello, I am studying learning, education and technology at the University of Oulu, Finland. I have already stayed in Philadephia for one year for my Fulbright Fellowship at the University of Pennsylvania. I am looking for housing at Maastricht for my two months internship from May 8 to July 15. Since I am self-sponsor, I have a tight budget. Hence, I wanted to find affordable accommodation. I prefer the shared room and fully assure for decency and friendly experience with me.
