Absolutely fantastic location on a small street lined with cafes near Piazza Navona. We walked nearly everywhere and enjoyed the Roman street life. Patrizia was an attentive host and was helpful in setting up airport transfers (50 euro, btw).
One of the most important criteria in selecting this unit was the fact that it was air conditioned - important in Rome in July. We arrived to find that we were in another, larger unit in the same building, but without AC. Apparently a guest before us clogged the plumbing and the unit was unavailable. After discussing with Patrizia (after we arrived) she went out and purchased fans which made the heat tolerable. But for that one issue, the apartment was grand, comfortable, and historic.
