Hotel Central Inn am Hauptbahnhof

We picked this location based on how close it was to the central train station, so we could get around Berlin. It was extremely hard to find, because the building is not well marked, and looks like run-down apartment complex. We had to take a dumb-waiter sized elevator to get to the receptionist, who seemed less than pleased that we arrived at 5pm. The room was clean, but smaller than what we've expected. We had to leave before breakfast the next morning, but it was easier to go to the nearby cafe.
