On a recent stay at FS Firenze in May, rooms were stocked with Lorenzo Villoresi ”specially created for Four Seasons” with citrus undertones which I found very well matched to the location. I don’t know what possessed me to do so, but I asked housekeeping whether there were other options and sure enough there were! My room was then stocked with additional sets of Sodashi, Bulgari au Thé Vert, and Bulgari au Thé Rouge. Quite impressive!
Somewhat less exciting, but FS San Francisco Market Street offers Erno Laszlo products. Quality seemed decent, but packaging left a lot to be desired…
