First, there is no sound privacy between the units. The unit I stayed in had dangerously wired electrical. The lights would power on with the refrigerator compressor. The outlets crackled. It was always under voltage but would blackout every few hours. There were no towels or a garbage can.
What made my stay truly horrific was listening to the couple next door beat each other up night after night. Oakland police showed up twice. The host made no attempt to remove the couple.
