We should build the equivalent of military messes but for civilians. Private bedroom and shower, and communal eating and living spaces. It's extremely social and would be perfect for young professionals.
Usually the shower, bathroom, and kitchen are in common, the former one on each floor. Usually there are paid professionals cleaning them regularly.
I don't consider them a bad accomodation. It's the equivalent of a school dorm. I wouldn't necessarily want to live there if working full time, but that's just preference.
You have to be an adaptable and accommodating person though.
