Rented Apartment

My friend shifted apartments today. But her new rented place is full of small but irritating defects and is real dirty. She said the owner actually claimed that he had cleaned the place and the defects are no problems at all. May I ask the owner a few questions? Are you sure that a bed missing two legs is safe for sleeping? Are you willing to sleep on your words? You said the place had been cleaned but why is it that I wiped the cupboards with a white cloth and ended up with a black one? Why can't you at least be ethical when renting out your apartment?
