I stayed (with my wife, 1 yr. old daughter and my parents) at Barbara's "Monti - Zingari Luxury Flat" for a week during our trip to Rome. Barbara was very responsive to all my queries. She arranged for our rides from/to the airport. Barbara had her friend receive us at the apartment. She was flexible enough to let us stay on as our flight was in the evening. The location of the apartment is just perfect - with many places in walking distance. The apartment itself was quite spacious with all the adequate facilities - she was kind enough to put some refreshments in the fridge. There are a couple of things to note for people with baby strollers. We had a stroller which was small enough to fit into the apartment lift - it might be a difficult to fit in a bigger one. Also, there are a couple of steps that lead up to the lift. Getting out of the lift at the apartment floor with the stroller were cumbersome at times.
Apart from this, it was a wonderful stay. The air-conditioners kept us cool in the hot Roman weather. I would absolutely recommend Barbara's apartment to anyone (other than families with big strollers/prams).
Cheers.
