I am reaching Munich Hauptbahnhof, Germany by 00:30 am from India. I need to reach Max Planck Institut für Astrophysik, Karl-Schwarzschild-Straße, Garching bei München, Germany. Since it is late night, I plan to take a taxi from Munich Hauptbahnhof (roughly 20 kms).
I intend to ask the following:
Approximately how much will be the charges for an economical ride (single traveller)?
What is the best way to book the taxi in advance (preferably online) and being economical?
