Patrizia was so patient, waiting for us to arrive half an hour later than expected due to delayed service at our rental car drop off. She was very helpful about the apartment and also about local restaurants (although I'd skip the one just on the corner on the same side as the apartment, a few doors towards Piazza navona - the food was more touristy and the experience far less authentic than her other suggestions). The apartment was fabulous - spacious and clean with a good bathroom. The double shutters/windows in the master bedroom do a good job of shutting out noise and cigarette smoke from the cafes on the street below. the twin bedroom in internal so very quiet, but the air conditioners in both bedroom did an excellent job of keeping the rooms comfortable without much air circulation. And the location is truly superb - in the most characterful part of Rome, to my mind, and walking distance to everything (even for my 4 year old with a broken arm). Patrizia also arranged a private large car to take us to the airport, which was great value in that we trusted her choice of company, and it was the same price (or less) than a taxi and far less stress on a rainy morning with kids and luggage.
Couldn't fault the apartment and will recommend to anyone and everyone heading to Rome.
