Band practice studios - Berlin

i need to find a good band practice studio in central-ish berlin. it has to have a professional standard backline and pa. i'll need to book it for 2 weeks solid. any ideas?

I used to practice in a place called Bunker. I do not know how "professional" you need the back line and PA, we played for fun.

Nosiy Rooms Warschauer Str 70 I think - ok in their hire all you need - i go their when we have smaller bands over for gear hire and for them to get a little practise in before the night.
