Right now you're facing a wall. Turn right and move forward. Now you can see a window in front of you. Turn right to exit the washroom. Now there is a large opened door on the right side. Move towards the opened door and exit the room. Now you're facing a closed white door and on the left you can see a staircase. Get down the stairs. Stand on the second step where you can find two potted plants in front of you and that is the end point.
