Continue until you get to the Sistine Chapel atop the staircase. Should you wish to use the restrooms, you will find them at the bottom of the staircase. Entering the Chapel, reach the center or the back of it to have a complete view of the frescoes. Looking at the Last Judgment above, the scenes from the life of Christ are on the right, the scenes of the life of Moses to the left. The fresco "Calling of the First Apostles" by Ghirlandaio is located in the third compartment on the north wall on your right.
