We stayed for 5 nights at this apartment, 4 adults and 2 children.
The location is great, right in the historical center, just a few meters away from the Colosseum with many options in public transportation (buses, tram and metro) and lots of shops and restaurants nearby. Even though it is located on a busy road, the apartment is quiet, with windows facing the courtyards.
The place itself was very clean, spacious, and counts with good amenities such as a nice kitchen, washing machine, fast wifi etc.
Paolo was very flexible in greeting us late at night upon our arrival and letting us leave our suitcases in the apartment during our last day so as to enjoy the whole day.
I would highly recommend this apartment for people visiting Rome.
