Answer:
No indoor plumbing, sewage in streets and constantly filthy
Step-by-step explanation:
Back in Medieval times there was no such thing as a toilet just a relief bucket that you squatted on and then tossed it into the street.
Not only was there peoples feces in the street there was also animal droppings, back in those days you either walked or rode a horse which in short they would leave piles in the streets that everyone stepped on.
also it was hard to keep clean because more than half the time the people in Europe only bathed twice a year because the church said it was unholy to bath to often.
Fun Fact: Did you know the Vikings actually bathed almost every day (and the English said they were heathens)
