Incredible apartment and location. My wife, son (12), and I stayed there for 3 nights in August 2017. The Colosseum and Roman Forum are within a 1-2 minute walk. Great restaurants and cafes are close by. Additionally, there is a grocery store 1-2 minutes away that is open 24X7.
We stayed at Sfefania's place during the Lucifier Heat Wave in which it was over 100 degrees Farenheit in Rome each day. Thanks to Stefani's reliable air conditioning, we were able to find respite from the heat, as well as sleep comfortably throughout our stay. Her apartment was comfortable for the three of us and was a great change after we were all crammed into a small cruise ship cabin for the week prior to arriving in Rome.
I plan on recommending Stefania's apartment to anyone else I know going to Rome.
