We flew out of Chicago O'Hare on a Sunday night on Lufthansa. We arrived the next morning in Munich, Germany. Munich has a very clean, quiet, and modern airport. Very nice. We had a little time before our connection, so we took a few minutes to explore.
Munich Airport had these neat napcabs. You pay with a card and can take a nap during your layover or before you head out to explore the city. One was being cleaned while we walked by, and it looked quite nice and clean.
