Ich (und mein hund Alfa ) suchen ein zimmer

Hello everyone.
This is Amir , I’m 21 years old, Im a musician and student of SAE Berlin.
Im looking for a room/apartment to live in from first of September. Preferably a 20 m room or an 40m unfurnished apartment with the maximum budget of 650 euros. Perfect locations would be Kreuzberg, Schöneberg, Friedrichshain,Tempelhof, Köpenick, Neukölln but im open to any other locations that suit me)
I will be moving with my dog Alfa who is a 4 years old Rottie that is a well-trained and supper friendly dog (always like to be petted) , she is clean and doesn’t shed.
About myself I love exploring nature with alfa, I don’t like partying at home. I will be a friendly roommate who loves to cook, for sure we will be spending time watching films, grab some drinks and I will be very adaptable and flexible with different situations however we all need our private time. I know fluent English and German level B1.
It will be a pleasure to hear from you and to spend some good times together 😊
