You are facing a door with bars.  If you turn around you will see a wall with 2 plants and to your left you will see a wood door.  You are going to enter that doorway.  You are going to enter that doorway and veer to the left.  You will see to your right a piano and a seating area.  To your left there is going to be a huge cement wall.  You are going to go in between the first part of that cement wall so you will be passing with the cement on your right and there will be some wood steps on your left.  You are going to go slightly forward and stop in front of a wood door.  And you are done.
