Standards of living were vastly different back then. It used to be the norm that 6-7 people were living in the same room, and apartments were about 22m² [1]. Toilets were outside the apartment. etc. Since then, old houses were upgraded and massive amounts of new houses were built to accommodate a rising standard of living.
