Follow the Highway until the end. At Munich west turn right, direction Innenstadt/Center until you reach Karlsplatz/Stachus. Turn left on Altstadtring on Oskar-Miller-Ring. Go through the tunnel to Prinzregentenstrasse. At the Haus der Kunst (museum of art) take the road on the lieft side into the Wagmuellerstrasse. The 2nd street on the left is the Liebigstrasse.
Public transportation coming from the airport:
From the airport, take the city train (either S1 or S8), then transfer at the Karlsplatz/Stachus stop into subway U4 or U5, and then get off at the "LEHEL" stop. From there, it is only a few steps to the Hotel ADRIA.
