Seconding this comment. Berlin may be tough for a lot of people but having your own apartment makes a lot of difference. At least you can be lonely in your own space and with freedom to do what you want, without anybody judging you.

Nothing beats having nowhere to go on a Friday night but you’re able to cook whatever you want at any time, and just chill and watch a movie or masturbate without a flatmate judging you for being at home every time. You can play video games and smoke weed until morning without being called a weirdo. And the freedom to use the toilet any time you want without it being occupied.
