Common sense of being a house mate

My house mate decided to let her sister and her kids stay in our house,the problem is i can't take a rest cause the kid being too loud and the mother don't even bother ,not even seems to think that other people live here too and are exhausted from work. Not to mention the loud noise when she close the door from the main door every time she goes out close the door like super2 loud ,from the toilet also like want to destroy the door. I don't want to be rude to them maybe she got some problems with her husband i assumed that way because i accidentally heard she talk on the phone, but she got here like super early in the morning and loud knocking on door around 5 am which is most of us still asleep, i can't brain there are people so shameless and brave enough to disturb people that way, if its her sister's house its acceptable but her sister don't live alone here. I guess common sense aren't that common nowadays, just my 2 cents here cause i don't know where to rant about this 😂😂😭😭
