Looking for a flat share from 9/11

Hi my name is Théo I actually live in Lyon in France and I'm moving to Berlin on the 11/09, I'm looking for some fresh air and to expend my knowledge of the wold basically.
I'm a wine sommelier here in France but I plan to do something a little bit less strict here to discover another side of my job as a waiter maybe working in a bar or something.
On the other side I really enjoy listening to music and I'm also a part time music maker.
I'm kind of starting to lose hope honestly concerning the accommodation I'm gonna be able to find before coming here if that's something that can even happen, I have nothing more than my trusty words to let you believe that I'm able to pay rent, I have savings I can even pay 2 months in advance if that's something that makes you relief.
Thank you very much for your time :)
