This is a nice apartment in a great location. My family of five stayed there for three nights and we were very comfortable. The combination of AC and room fans kept us comfortable despite the hot temperatures outside. The location is PERFECT. You can walk to Campo di' Fiori in 5 min, Piazza Navona or the Pantheon in 10 min. With a 20-30 min walk you can get to the Vatican, Trevi Fountain or the Colisseum. Vei dei Cappellari is a cute little street with several excellent restaurants, and a grocery store nearby. Fortunately, you are just far enough way from the Campo that you don't hear the noises at night. In short, a perfect location.
Inside, we had everything we needed. Full kitchen (except no oven), TV for watching the World Cup (!), and plenty of beds and space for everyone. Highly recommended!
