This was a great choice for us, one that i highly recommend. The flat itself is beautiful, tastefully decorated, and overall it felt like the right place to be during our time in Rome (that jacuzzi is so nice to have at the end of a long day out). The location itself is a great one - lots of nice cafes and restaurants around Campo de' Fiori (a lovely one just 20m down the alley); a number of interesting museums and landmarks within walking distance; it's relatively quiet at night, but you are just around the corner from the piazza, lively well into the night.
Above all, Francesca and Alessio were always on hand, they took care of all necessities, gave very clear instructions. They were there when we had questions and requests, and were very generous with us. We had a nice stay, and I am confident others will too.
