Looking for room/flat: from 31/Jan on (for 4-6 months)

I’m from Sao Paulo, Brazil and work in an art gallery in Charlottenburg. I’ve been living in Berlin for 7 months now and I’d be ideally looking for a long-term lease. Anmeldung ideal, I’d also ask for a contract. I’m cool with a WG, would also enjoy taking care of someone’s apartment while they’re travelling or something like that. I love music and have lots of fun listening to it. Still, I’m relatively introverted, so I tend to be discreet. I dislike disturbing others and also value my own privacy. I really enjoy intellectual/philosophical banter and I do have an overall good sense of humor. :) I smoke tobacco occasionally and also enjoy drinking. A bright apartment with windows and white walls would be a perfect one. I’m 100% ok with living with cats, dogs and plants, of course. I can speak a bit of German, but can communicate better with English.
