A guest room showcases Robert John Thornton’s botanical prints.
Housed in a 16th-century mansion that once belonged to the noble Borghese family, Hotel Vilòn opened its doors in 2018 after a dramatic makeover. (Still catering to nobility, the getaway reportedly hosted Prince Harry and Meghan Markle, in town for a wedding in September). Rome-based production designer Paolo Bonfini crafted the interiors, which include a glamorous bar and 18 guest rooms, their color schemes inspired by 18th-century English scientist Robert John Thornton’s botanical prints.
