It is located along the street which serves as the northern access route into the city walls and is the main connection between Piazza Fratelli Rosselli, in the suburb of Porta Nuova, and the historic center.

The lateral facade facing Viale Porciatti includes two smaller, tiered sections — one rectangular and one hexagonal with a projecting turret — that connect to the more subdued rear of the building.

[4] Original elements include the attic's red ceramic hexagonal tiles and the side chapel's terrazzo flooring with geometric patterns and a carved wooden portal.

Villino Pastorelli is considered one of the finest works by architect Porciatti, the most significant local figure and the leading representative of eclecticism and later Art Nouveau in the Grosseto area.

[5] Quattrocchi (2006) describes the villa as a "fairy-tale castle featuring a profusion of Anglo-Gothic elements, also evident in its intricate floor plan, which directly references examples of English 'domestic architecture'".
