It could be so nice: You've found a great apartment, maybe even a shared apartment - but somehow things don't seem to be working out together. Sometimes it's just disagreement over some important things that causes friction. Most of the time it's not that bad, because you can (hopefully!) talk about everything. At least that's part of good manners in a shared apartment.
Put dirty finches on your doorstep
The floor in the kitchen is sticking, the leftover spaghetti on the pot stubbornly sticks to the iron even after the third rinse, and hair of all kinds has gotten caught in the shower drain... Ouch! If it's because the house cleaning always ends up with the same candidate, a cleaning plan can be helpful! This way everyone knows when it's their turn to do the dishes, take out the trash, clean or maybe do the shopping for the shared apartment.
It is also helpful to introduce punishments if one of you ignores the plan, for example next time you should clean the toilet with your own toothbrush or mop the hallway naked in front of your apartment 
Warn about fun on the toilet
A shower schedule can also be as useful as a cleaning schedule. If 5 people want to go to the bathroom before college at the same time, at least 4 roommates will be late for class. Clarify who wants to take a shower on which days of the week and when.
Likewise, please warn your roommates before you have to go to the toilet 
You can do this very subtly by asking if someone needs to go to the bathroom. This way you avoid your roommates having to go in right after you and asking for a gas mask.
Agree over the internet/telephone
Fortunately, these days we can use the telephone and the Internet at the same time and no longer have to hang up the phone just because we want to access the Internet - like we did back in the 90s and early 20s with a 56k modem. But we all have to agree on the tariff in 2015.
One person wants provider Then sit down together and look through the different providers. For example, there is currently an attractive offer for telephony and internet specifically for Unitymedia students .
Announce distinguished visitors
No matter if you want to bring a date home, invite a few fellow students over to cook, or throw a party, ask your roommates if it's okay with them or at least let them know briefly what you're planning.
Nothing is more annoying for your roommates when they're trying to prepare for an exam and you're making fun of yourself in the next room and yelling at half the house. So: Quickly clarify whether Ramba Zamba is possible on the planned day and the house blessing is guaranteed not to go wrong!
Never fuck the flatmate
Speaking of sex: If you want to avoid trouble in the long term and be on the safe side, stick to not fucking your (residential) colleague, just like in the office.
It still takes two, but let's be honest - one always falls in love! Then you can, for example, forget about bringing other (sex) partners home, because then discussions and arguments due to jealousy are inevitable.
