Henrik's place is great and is exactly as he says! We met Sven, who is super friendly! It is really close to the u-banh and Alexanderplatz but also a pretty neat trendy neighborhood. It is nice and quiet in the nights when you're ready to relax. There is a really neat Mate tea bar next door that we would highly recommend you try! Gave us the energy to walk around Berlin! Henrik also sent us a bunch of great info about Berlin when we confirmed the booking which was super helpful!
