We stayed at Barbara's place on Via degli Zingari. She was very responsive to my inquiring emails before arriving there and received us at the apartment @ the appointed time. She showed us around the apartment and left a useful FAQ sheet. She arranged for our taxi back to the airport and generally was a great host. She has family who live next door, so even if we never had to call them it felt good to know.

The apartment was neat, large enough for our family of 4, had all the appliances, and was centrally located -- 5 minutes walk from the Colosseum and 15-20 minutes walk from Trevi and Trastavere. The area around the apartment has a bunch of little stores flanked by 2 plaza's. Plaza Zingari has an amazing Gelato place (Fatamorgana, completely Gluten Free too if you need it -- we tried every flavor I think). The other plaza has a Bar and was frequented by many a young couple in the evenings.
