Looking for long term room to stay in Berlin

About this listing

Hi!) I'm Ukranian refugee finding my feets in Berlin now. I have few weeks when me Zoriana 25yo and Vitalina 24yo don't have place to crash. I started to learn German on curses in Kreuzberg. So either looking for short time hosting or long term room to rent up to 400 eur or apt up to 600 eur with contract(cause I need it to be payed from state). Would really appreciate any help.
