Craigslist is shady as ****. I wouldn't worry about him hearing you pee. I'd worry about him raping you, drugging you, using drugs in the house, making drugs in the house, bringing over shady people and partying all night long, maybe he's mentally ill, maybe he has a short temper, maybe he's a sex offender, etc etc

Craigslist is sketch. I wouldn't move out with someone I don't know.
