You'll begin your audio tour from Berlin's Marienkirche on Karl-Liebknecht Straße in the city centre.
From the major station of Alexanderplatz, to which the U2, U5 and U8 underground lines run, the S5 and S7 Stadtbahnlines and the M4, M5 and M6 trams also travel, walk from the station toward the famous television tower. Either walk through one of the passages or around, the church is near the fountains on the other side. You should be able to see its green singular spire with ease.
If travelling by tram, the M4, M5 and M6 will take you directly to the church, just exit at the stop Spandauer Str/ Marienkirche.
Parking is a little more difficult. There is some on street parking in front of the church, otherwise there is normally ample parking on Karl-Marx-Allee which is a ten minute walk away from the start location.
When you are at the church, I will be waiting for you in front of the doors.
