When I called him out on bringing strangers into my space, he blew up at me and took a chunk out of my deposit, claiming that I hadn't cleaned the kitchen despite the fact I hadn't used it in over a week and that wasn't part of my lease agreement. When I contested, he said "your Berkeley parents won't give a damn about this money." He didn't return my deposit in full and threatened to call my new landlord in an attempt to sabotage my new lease.
DO NOT LIVE WITH HIM! His house is disgusting, he doesn't clean up after himself or his child, and he is incredibly disrespectful.
