Looking for a room or apartment for October

Hello there! I'm looking for a place because I need to move from my current apartment soon, but I can only move to my new apartment in the beginning of November. I work at a marketing agency and I work every day from the office so I don´t spend much time at home. I'm 26 years old and moved to Berlin 3 months ago upon finishing my master´s. I like my surroundings clean and tidy, I enjoy being with people but also respect other's spaces :) I would just bring 2 suitcases so I would need a furnished place for those approx. 3 weeks. Thank you very much in advance! I have all the necessary documents (schufa (jetzt beantragen) (request now) , payslips, etc).
