@Dorian143 I don't think you need to take pictures. AirBnB CS won't care.
However, you have received two reviews that implied that your hosts were not happy. Had I received these reviews, I would have wanted to know how I could be a better guest. Assuming that these were rooms in a person's home, are you tidy in the shared bathroom? Leave the seat up or down? Your towel on the floor or draped over the door? Did you make use of the kitchen and leave crumbs on the counter or take a dish of food to your room? Did you eat in the room? Did you leave food containers in a bedroom bin that did not have a liner/bag or did you put them in the kitchen bin? Did you leave off your shoes inside the door but dripping on the floor and not on the mat or shoe tray?
My cousin is German, and her housekeeping would cause most Americans to roll their eyes at her fastidiousness/fussiness. So, think about your actions while you were a guest. Would your grandmother or mother approve? If the host seemed friendly (up until their review) ask for some clarification on how you can be a better guest. Apologize, don't argue. Just get their perspective. Oh -- my military spouse's comment was "What would your drill sergeant think?"
