I'm renting now a one room apartment, and it has no AC. It has one window which often allows sun to get in the room. Where i live temperatures in the summer can go up to 40C (104F), so I would like to know, do any of you have any working tips for how to cool down apartment (or at least myself)? I can buy something not ultra expensive like a fan or humidifier, if that helps, but AC is out of question right now.
