We were greeted upon arrival by Ghily who gave us a quick tour of the apartment and offered some lunch & dinner suggestions (which we took, and we're very happy with our meal). The apartment is very nice, modern and spotless. The location is excellent, especially if you plan on doing some shopping on the Via del Corso. The lovely Piazza del Popolo is a 1-2 minute walk, 5 mins to the metro, about 15 mins walk to the Trevi Fountain, the Pantheon, or the fountain of Neptune (with several amazing Basilicas along the way), you can see a lot of Rome within an easy 15-20 minute walk.
Excellent stay, I wouldn't hesitate to book here again!
