From the airport, take the city rail line S8 or S1 to the main railway station ("Hauptbahnhof"), then change to underground line U4 or U5 until you reach Theresienwiese. (It takes approximately 8 minutes to walk from the main railway station to the hotel.)
If you are arriving by car, follow the Mittler Ring towards the main railway station ("Hauptbahnhof"). From Arnulfstraße, turn left into Paul-Heyse-Straße. Follow Paul-Heyse-Straße and at the 3rd junction turn right into Landwehrstraße. You will find the hotel on the left-hand side. The underground garage is located right next to the hotel entrance.
