The lounge and guest kitchen are homey touches, but the real attraction of this cozy lodging is the roof garden, a leafy retreat where the greenery is backed by the town’s brick towers and tile rooftops. Parts of an Etruscan wall enhance the historic character of the old house, but rooms are charmingly up to date, filled with comfortable, attractive furniture handpicked by the friendly owners. The Piazza dei Priori is only a few steps from this stylish haven.
