Nah, he's got it pretty accurate. The average Roman (Plebian) lived in a tenement called an Insula (Insulae.) They had no plumbing or sanitation to speak of, and if you were lucky you had an exhaust vent for cooking. Fire and disease was common. Insulae were often poorly constructed, and built to 9 floors before regulation limited the height. Collapse was the watchword of the day. Some were better than others and offered larger rooms, but you were probably packed in with 400 other people, all with no plumbing. Public facilities were full of parasites. You bathed and shat with the sick and the well. There's references to ostraca and tersorium being used for wiping ones ass (pottery shards/rocks and the "sponge on a stick") but those are referenced to only marginally in what we know about the time. The sponge was said to be cleaned in a communal bucket of vinegar after use, which doesn't really kill the contamination. People probably used whatever they had to wipe their ass, including hands. Paper would have been far too expensive to use, it's only modern manufacturing scale that allows us to do that. There were no street cleaning services, so the streets were coated with dog and horse shit, and probably people shit as well for those that didn't want to use the latrines, which sometimes required payment. If you were a member of the Equestrian or Patrician classes, you could probably afford a domus or a villa (a nicer detached home / country home) or larger insula that had plumbing and other amenities. Legionaries had barracks. The house in your video was most likely a vacation home for some rich citizen of the City of Rome. Plebian class didn't live there.
