Rats living under the floor boards and bathtub, mushrooms growing out the walls, water leaking from the second floor filling the walls with water bubbles. Windows not sealed so it's open to the elements, you live with bugs of the environment. Landlord will swap your broken oven for a roach infested oven instead. Ants and other creatures live within the walls and will crawl out of the gap between the wall and floor. Very quick to receive rent payment. Very slow to fix anything wrong with your apartment.
