ok, i have some firsthand experience...... 5 months in a 6x18 box with 3 other room mates while on deployment..... it sucks.... but you cope, or you put the smackdown...... a lot of people don't realize they are being disrespectful. now if they do, and refuse to do anything about it, then you need to lay the law.... it might be easier to move out, but also finding somewhere better might be hard as well.....
let them know that you will inform the landlord, if the landlord refuses to get involved, inform them you are going to the cops..... see how quickly things change.... sure... you might think you are being a snitch, but it is at the cost of your sanity/sleep... which isn't cool....
