What are the similarities between the cities of the 16th and 17th centuries and the medieval ones, and what is new in their appearance?

The similarities were unsanitary conditions, the city and the Middle Ages and the early modern times were dirty and unsanitary.
Another similarity is the relatively low% of the urban population in the total population, as well as the presence of walls and fortifications, then this was still relevant in case of sieges.
What changed? There were more books as printing houses appeared at that time. Colonial goods appeared, the result of the development of foreign trade with the colonies in those years. There were more universities, in addition to Catholic churches, Protestant churches appeared in cities.
