Nice place, quiet and well-appointed, close to the old Roman sights. Great deli across the street, supermarket virtually in the building. For eating, good places nearby: Vecchia Roma round the corner, Mercato Centrale in Termini station, Trattoria Monti 5 mins away.
Termini station close by for day trips, or to get to the airport. Don’t miss Palazzo Massimo alle Terme for the frescoes.
