I was staying at Jacopo's place for the second time, and my very positive impression from the first time was more than confirmed. The appartment is large, well-equipped, and very quiet. It's location is great: in walking distance to Termini station, but at the same time not far from Monti with it's nice bars and restaurants. Most places in Rome can easily be reached by walking or by public transport, e.g., from the nearby metro stations.
