Sasa was available and showed me around the apt when I first arrived. She was full of neighborhood recommendations.
The neighborhood for me was terrific. It combined a local population served by laundries, mini-markets, hardware stores and cafes with an in-coming city-wide population attracted to the restaurants, bars, book shops, clothing stores and antique shops of the district. There are gathering spots and quiet streets. The area is not overrun by tourists and is within walking distance of many of Rome's historic sites and museums.
