There is a lot of history swirling around the cobblestones and shuttered windows of Via Margutta. It’s on this ochre-hued street that Stravinsky and Fellini made their homes, Picasso fell for his ballerina wife and Gregory Peck set out to woo Audrey Hepburn in Roman Holiday. And it’s now home to Margutta 19 – a refined boutique retreat in a beautiful palazzo.
