Walk straight ahead towards the wall with a small chest on the left side of it. Turn right and walk down the hall with the dark path. You'll walk by two wicker baskets on the right, a pair of open double doors on the right as well. Keep walking straight, there'll be 3 steps at the end, walk up those three steps and you'll stand just in front of an art piece on the ground, an interesting design. To the right is an open doorway, you're done.
