You're standing in front of a window in a room with a lot of chairs and a fire place, if you turn to your right you will notice there's a small table in the middle of the room with two ottomans. Walk towards that table jumping over the chairs and right in front of you there's going to be a standing closet on your left and an open door next to the closet on the right side and there's another doorway on the right side of the wall, so jump over the table on the middle and walk towards those open doors there and turn to your right side, and walk through the open door on your right side, and keep walking through that hallway, and on your right side you will see there are two pillars and the beginning of a staircase. Walk towards the furthest pillar, wait, actually take two steps downstairs and then go back to the base of the stairs, and once you're standing in between both pillars, you're done.
