After the touching down from the shortest and most comfortable flight of the whole trip we checked in with the tourist desk for our Berlin Welcome Cards. These cards gave us unlimited rides on public transit and came with a handy booklet of attractions which honored the cards for discounts. We never did seek out any of those discounts, but the transit pass was pivotal for getting around Berlin. This was especially true since riding public transit appeared always to be purely on the honor system! But a quick ride on the U2 from the central hub of Alexanderplatz got us swiftly to the central neighborhood of Eberswalder and our AirBnb.
