Secure Parking in Berlin

Hi,

I'm on a middle-aged boys weekend to Berlin in a couple of weeks and am using the opportunity to have a bit of a road trip. Other than a fleeting visit for football, I've never been to Berlin so a little unsure what I am letting myself in for.

I am trying to find secure parking where I can leave my car for a few days near Prenzlauer Berg (10437). Is anyone able to advise please? The car usually only leaves the garage on sunny days so not keen on just dumping anywhere.

Thanks!
