Margutta 19, the latest addition to the Rome Luxury Suites boutique hotel collection, sits just across the road from Federico Fellini’s old apartment. It houses 16 stylish rooms overlooking cobbled Via Margutta—an ivy-decked artists’ lane just a strut away from the fashion shopping drag of Via Condotti—and the secret garden of the hotel’s Assaggia restaurant, a hot ticket among Roman fashionistas for its “tapas” approach to Roman classics like spaghetti alla carbonara.
