We strongly recommend this B&B. We stayed eight nights and found it very enjoyable, as well as centrally located on via Cavour. The bed and pillows were quite comfortable, and there's good water pressure and constant hot water in the bathroom. Lighting is excellent, which is not always the case in European hotels and guesthouses. Domenico is very pleasant and helpful. You can easily walk to many attractions -- Colosseum, Forums, Palatine, Campidoglio, plus museums and churches near Termini Train Station. Also right near Cavour metro station and useful bus routes. The only negative aspect is that you must pay in cash, which is inconvenient for a stay of more than a few days.
