Vault and walls are decorated with polychrome and gilded reliefs that simulate flowering branches and branches inhabited by birds, on a light blue-gray background. The vegetal element recurs above the slender cornice and in the carvings of doors and over doors. The color scheme is delicate with bright and bright colors: ranging from light green-beige, teal and dark green of the leaves to pink and carmine red of the mottling of most of the petals, to intense blue and blue of some flowers; everything stands out against the light blue-gray background. The style seems close to that of the stuccos made in Genoa and Liguria by artists from the valleys of Italian Switzerland, near Lake Como. The themes of the three overdoors, in accordance with the dictates of Rococo fashion, are also found in a living room of the Apartment of the Ladies on the first mezzanine floor, where the plastic decoration is performed with extraordinary technique and refinement.
