The rooms of Grotta Giusti have been totally renovated. Today, each detail is a narration of Tuscan art, the nature of the park and the history that has been made inside these walls. The harmony of trees and plants is echoed in the wall decorations, paintings, and prints, in the elaborate and splendid shape of the chandeliers and appliqués.

The fabrics and upholstery materials have the texture and colours of bark and leaves. Wood shows its most precious grain, the metals used are in the warm colours of antique bronze and wrought and aged iron. The light filtered through the curtains is dappled by the leaves, and the marble in the bathrooms conveys the same feelings as the limestone that is sculpted by water inside the cave.
