The Berlin public transportation system is clean and efficient. The bus, the U-Bahn (underground trains) and the S-Bahn (surface trains) are all interconnected. You can easily transfer from one to the other. I bought a 7-day pass for 30 euros ($34). I have used the public transport to get from the airport to my hotel and to go to several sights and to go to FKK Artemis and back. Artemis is about 5 miles from my hotel in the city center. A taxi would probably be 30 euros one way.
The transit system has no gates or turnstiles or ticket reading devices. You simply walk on. You are supposed to buy a ticket or a pass, and they have inspectors who can ask to see your ticket and fine you if you don’t have one. I have not yet seen an inspector. This system works on the assumption that 99% of the riders are honest. I wonder how this system would work in New York City.
