I was at Andreas's place for 4 nights and indeed I had a comfortable stay. Easy location, well situated close to but not directly off of the main intersection that has both ubahn station and tram car stops. Lots of places to go eat near by as well. Close to notorious Berghain club.
Andreas is easy to communicate with, and considerate of small details, like having a plethora of hotel style amenities one could be in of when one lands, which I appreciated lots. Thanks again, Andreas!
