From Piazza Venezia, having the Vittoriano monument at your back, head right to cross Piazza della Madonna di Loreto and then continue onto Foro Traiano. Walk straight along the road until you reach the stairs at Via Magnanapoli. Upon taking the stairs, continue onto Via Magnanapoli and then turn right into Via Quattro Novembre. At the roundabout, go left and take the second exit onto Via Ventiquattro Maggio, which will lead you onto Piazza del Quirinale. The Palace is the massive white building looking out onto the square.
