Find building 24. If you arrive by Metro, follow the pink line from "Islands Brygge" station.
Enter the building through this door. It says "Bygning 24, Njalsgade 128" above the door.
Go to the elevators on the right and push the "Up" button.
Take the elevator to the 5th floor.
When you exit the elevator, enter the door on your left.
Go almost to the end of the hallway.
My office is on the right side of the hallway (room 24.5.58).
