Portable AC (Downtown Toronto)

Please help me out. I stay in a room which doesn't have airconditionig. All I have is window which faces a wall and it's getting really hot. The temperature goes above a 100 degrees in my room. I'm unable to work and sleep. I can't afford to move or buy an ac. Please help if you have an air-conditioning unit which. You can spare. Thank you for taking the time to read my post. Best wishes.
