27 Year old female looking for a cheap room for rent

I am looking for a room for rent so I can get my residency permit for Germany. I already have a job but as the permit requires established residency, I am in a bit of a hurry to try and find a place before my temporary visa ends. I am looking for a cheap place, regardless of it being a whole flat, a single room, or a shared room. I am looking at a price range of maxiumum 250 euro a month rent. If anyone has a space like this availiable please contact me via this site and I will send you my email or phone number so we can be in more direct contact. Danke.
