AN INTERESTING discussion started on Reddit, where one user asked the apartment renters what was the most shocking thing that tourists left behind after leaving the apartment.

"One year, someone relieved himself, wrapped the poop into a blanket, and left the blanket on top of a closet," said the author of the post and started the discussion.

Most Reddit users complained about the tourists who leave the air conditioner on with open windows, but there were more disgusting examples.

"Air conditioner on with the windows open. And those who didn't leave anything like that, but they stole. Once, they offered money for Mediterranean tortoises. We refused, and then the next day, they stole one," says one of the comments.

"If you don't want poop in bags, don't rent to Russians. Their drains are known to be fucked up, and most of them poop in bags at home and piss in toilets. They throw away those bags at home, but in apartments, they leave them for you to deal with because housekeeping is included in the price. This is information from a girl who was doing housekeeping in hotels during summer," a Reddit user wrote.

"My grandmother was a renter. About ten years ago, a gay couple stayed at her place (males). They left bedclothes full of crap and blood," the other wrote.

"I'm only on Airbnb, so the worst that has happened to me was an air conditioner turned on. My girlfriend worked in a 5-star hotel one year, so she found poop in a bag," someone wrote another comment.

"Indians cook with hands and grab all the spices with hands, so there was salt in pepper, paprika in salt, and oil in both spices. They leave a towel on the floor where they've dropped food. So all towels end up on the floor. The entire apartment smells of curry for around three weeks after they leave," "The used dope syringes," "Speed," are just some of the comments.
