I'll be in Berlin starting January 4, 2016 and leaving (probably) on the last day of February. Who is your friend who is moving to Berlin? Are they on DA?
Okay, that's good that you told me. Maybe I should start looking for a place in Munich now. Although, I'm using a website called "AirBNB" to find places, which basically means I'd be living in people's spare rooms for a relatively cheap price. I saw lots of nice places listed for Munich when I last checked. But you're right, it does seem Munich is more expensive than other German cities. But it looks very beautiful.
The band is called Orbis. They have a Soundcloud page here:
