I definitely recommend Mr. Giancarlo and his appartment. He was welcoming and helped us with all the information it was needed.
The appartment is beautiful with all it's vintage furniture and has more than enough space for 6 persons. It is fully equipped.
The location I could say it is perfect. 2 minutes away by foot from the metro and Piazza del Popolo and from there on you can reach the heart of Rome in just 10-15 minutes.
To sum it all up, it is a great appartment for a family or a group of friends with everything in its proximity that i would definetly book it again when i will come next time to Rome.
Have a great day!
