Location, location, location. This flat is smack bang in the middle of Rome. We managed to walk to most of the main sites without using any public transport. It's right on top of excellent restaurants, Gelaterias & sandwich shops, a stones throw from the Pantheon & Piazza Navone but quiet enough to sleep at night with the double glazing! Air-conditioning, good shower, comfortable beds & a good kitchen for knocking up breakfast or a quick tortellini.
Francesca was a fantastic host and her printed guide to Rome was extremely useful. I'd recommend this place for anyone planning a trip to bellissima Roma.
