Question:

Why do we get charged for damage or loss in the accommodation we are renting?

Answer:

It costs money to repair and replace things. 

We try to narrow it down to the person(s) who are responsible for the damage. When this is not possible we have to divide the charges equally among all the residents of the apartment, depending on the location of the damage.
