If you’re lucky enough, you might find a parking spot in the side street called Ferdinandstraße. Don’t forget to buy a parking ticket – so you don’t get a ticket… If there is no free spot left, you can use the parking lot of the Kunsthalle (museum). It is right across the office building, Ferdinandstor 1.
Hamburg Central Station is only 650 meters away. All vehicles of public transportation that you could think of arrive there. Yay!
