Apparantly I have to tell people to leave my apartment in the same state as it is when you move in. Examples: Dont consume anything from the fridge. Close the fridge and freezer. Turn the lights off. Dont smoke. Dont do drugs. Flush the toilet. More under "Rules".
Clean the floor with the vacuum cleaner. Use the sheet for the couch, dont sleep naked on it. Put the cushions back in the couch after sleeping. Dont leave paper bags from 7-11 all over the floor. Dont leave wet towels on the floor. Dont drink my beers. Dont eat my cheese. Dont stalk my neighbours. The girls doesnt like it when you wait outside their door. Dont erase my saves on my video games, dont delete my saves, dont break my highscores. Dont leave bloody toilet paper on the floor. Throw toilet paper rolls in the bin. Dont leave unknown black stuff in the sink. Put the disc back in the case when you have watched a dvd.
Dont leave wet dishes on the kitchen table, dry them with the dishcloth and put them back on the shelfes.
Take out the trash when leaving.
Some of these are examples of things that people have done when renting my apartment and are guidelines to show what I expect. Im sure that theres a lot more to list, but I cant spend the rest of my evening writing them down, so please just use your common sense :)
