You will probably smell a whiff of roses emanating from Aquaflor well before you arrive. Inside the stunning 16th-century Palazzo Corsini-Serristori in the Santa Croce neighborhood, Sileno Cheloni creates scents that vividly evoke the Tuscan seaside or pine forests. Cheloni studied with a Sufi master in Cyprus and worked in Milan and Lucca to learn Renaissance techniques before opening this shop, made up of three rooms lined with wooden apothecary cabinets that display glass bottles. Large tables are piled with soaps in scents like tomato-leaf rose. Spend some time in the Parlor of Essences to create your own unique bouquet or learn about the rare oils that are used to fashion the signature fragrances.
