I had a bad experience with the shared bathroom. It felt pretty scary.
The light was sound-sensitive. It would turn off soon after I started showering, and it would not turn back on even if I made loud noises in the showering cell...... I had to either finish showering in the dark, bring my phone to use as a torch, or step into the center of the bathroom to turn on the sound-sensitive light in the middle of showering...... while anyone could come into the bathroom anytime from the hallway.
