It would be hard to convey how great an apartment this is, and how great a location. It is 3 minutes from the Campo dei Fiori, 5 minutes from Trastevere in one direction and Piazza Navona in the other, perhaps 10 from the Pantheon, and so on. And the apartment is utterly charming, especially the terrace. The only thing you might worry about is that it can be a little noisy in the evening, from the VERY chic restaurant down in the square below—but it's a fancy place, not a bar, so it doesn't last past maybe 10:30. Highly recommended.
