You are standing at the french doors in a very large dining room. Turn all the way around toward the fireplace and the 2nd doorway on the left of the dining room that heads into the hall. The fireplace will be on your right.  Take a direct left into the hall with the wooded floor. Then an immediate right following the only direction in the hall.  Continue in hall until you get to the stairway on your right.  There's a wooden stairway leading down and a wooden stairway leading up.  Take the stairway going down just a few steps.  Do not go all the way down the stairway, after 2 or 3 steps you have arrived at your destination.
