Sleep in style at two recently opened Italian properties—one in the city, the other in the country. In Rome's artsy Trastevere quarter, furniture and fashion designer Luisa Longo has transformed her family's 1960's villa, built around a palm-filled courtyard, into an intimate three-bedroom guesthouse, the Buonanotte Garibaldi (83 Via Garibaldi; 39-06/5833-0733; www.buonanottegaribaldi.com; doubles from $305). The inn's color-drenched rooms mix family heirlooms with Longo's own Matisse-and Kandinsky-inspired designs (bright silk bedspreads, lamps with abstract swirls), all of which are on sale in her adjoining atelier. • Just a 25-minute drive from Florence, the 50-room Castello del Nero (7 Strada Spicciano, Tavarnelle Val di Pesa; 39-055/806-470; www.castellodelnero.com; doubles from $735) reinvents the classic Italian villa. Designed by Alain Mertens (interior designer to Madonna and Sting), the 12th-century former nobleman's residence has Philippe Starck Ghost chairs set beneath family crests and frescoes, and ancient stone-framed windows hung with primary-color curtains.
