Looking for a Studio apartment for rent in Berlin, or a private room in a WG

REAL ESTATE
Hello everyone!
My name is Nazeeb Khan, 26 years old. I am a master student, and have been living in Berlin for over a year now.
I am looking for a Studio apartment for rent in Berlin, or a private room in a WG (max 2 or 3 persons, including myself), starting from the 1st of May. Location: Ideally, looking for something around Moabit, Wedding, or Kreuzberg. But, It can also be within A, B, or C. Most importantly, should be accessible by public transport, preferably S Bahn or U Bahn or Tram (I have to carry my bike to work/Uni).
Anmeldung: Preferable, but without anmeldung could also be considerd.
Duration: Short term or long term, does not really matter. But would be great to find something long-term.
Price: Can be discussed in private (please dm) I am also open to teaming up with you if you have any leads.
A bit about myself:
Flexible, not that much a party person, calm, and always keep the place neat and tidy. Also, doesn't smoke or drink, but eats a lot. Enjoy outdoors and conversations as well. 😛
If you have or know something, feel free to send a message. 🙂
Thanks a lot. Cheers!
Naz
