Affordable German class? (Berlin)

Hello! I just moved to Berlin 3 weeks ago to be with my husband. I am looking for an affordable German class. I do not have any experience with German. I only know a few basic words and phrases.

I don't have much to spend and I have only seen German classes that cost about Protected content and more. Anyone have any recommendations of something cheaper?

I live in Friedenau so I hope to find something not too far away. Thank you!
