Searching a comfy, small room, Neuköln or anywhere else in Berlin, both temporary or longterm

Heyy,
I am looking for a room to stay in Berlin for the summer! My name is Lara, I have been moving around for quite a while and trying now to settle a bit, seeing if Berlin is right for me. I like to spent my time wandering around to compensate a racing mind, I care about politics, even though I get overwhelmed by it. I like to read books, Murakami or post-capitalism theory, a bit extra. I also like dancing and going out, even though I do it less than I'd like to. At home I am quite calm, I like keep things tidy and clean but I am not bothered if others aren't. I think it's great if your shared flat evolves to be shared with friends, but nothing "must".
I like to chill with a beer or if I am feeling fancy with wine. Since I am back in Germany I have developed a strong addiction to Club Mate, which uplevels my hipster vibes.
I do like techno, but also classic, and some times I feel a big need for heavy rap to feel as tough as I truely am.
Cheers,
Ohh and I do graphic stuff and hand poke.
My price limit is 400/month.
