I nice little flat in the middle of Berlin. I can't comment specifically on the location since I selected it to be more convenient to a particular venue for a music festival (Kraftwerk Berlin), but I've managed to walk everywhere every day (about a 30-minute stroll to Alexanderplatz - the distances in Berlin are deceiving!) There were a few nights when the outside pedestrians woke me up (the bedroom window is facing the street on the first floor), but overall the stay was quiet, comfortable, and cozy. I mostly spent my time at the place sleeping, but Netflix did help to wind down, and the internet was reliable to do some work on the side. Great and easy communication, hassle-free check-in, and an overall feeling of "home".
