Three friends looking for a place

Hello!
We are Anne, Marta and Angel and we are currently subleting in Berlin and looking for a three bedroom flat or in a shared apartment with Anmeldung.
About us:
Anne is currently pursuing a master’s degree in physics at Freie Universität, Angel works as an architect and Marta is interning in an Berlin-based art-studio. We are hard-working and committed to our jobs/studies, so most of our time is spent working as well as learning the German language.
In addition, we cherish time spent in our apartment and really value a good living environment. We also enjoy experimenting with different cuisines, engage in discussions over a carefully curated playlist of songs, share hearty laughter while indulging in a TV series, and connecting with friends.
We'd love to live in an apartment but also open to a shared flat. We're ideally looking to live around Neukölln, Kreuzburg, Charlottenburg, Friedrichshain, Mitte, Tiergarten or Schöneberg for around 1200-1900 euros, but flexible on both for the right place. We'll most likely need a place where Anmeldung is possible.
