You will start by facing a brown or orange wall with a lamp above it. Turn to your right and you will see a bookshelf on the right side of the wall. Walk past the bookshelf through the open doorway. Keep walking forward until you've reached a flower plant on the floor on the left side of the wall with a white vase or pot. Turn to your left and you will see a large opening towards the staircase. Walk inside that and here you will see staircase going down on your right. On the left side of that is the staircase going up. Take a step on the staircase going upwards and once you're there, that's where you stop.
