I'm 18 years old and I’m looking for a place to stay in Berlin

My name is Isabella Barrera I’m 18 years old I was born in Colombia and I’m planning to move to Berlin to learn German. I’m looking for a not so expensive option. I’m very organized and independent. And I'm looking for an accomodation maybe shared with more than one pearson, but where I can have my own bedroom. I’m for roommates that are not a lot older than me, Trustworthy, that respects boundaries and that party’s but not every single day in the house, and also that is kind of organized, and not problematic . And also that we can at least talk virtually before moving in.
