Tennis classes in Berlin

Does anyone know of any tennis courses offered in the Berlin area -- ideally indoor due to current lack of sizzling sunshine? Thx.

Hi...I once played indoor tennis in Berlin and I believe they were also giving courses...I am not sure what's the place name, but I'll try to find out and will let you know.

Are you beginner or do you already play and want to get better? I haven't really played in years, but I am usually always up for tennis. Cheers.
