A huge benefit of staying at Giulia's place was the location. We were close to the city center with public transit close by.
And in case you don't feel like eating out every day, having a grocery store right behind you was convenient.
The only shortcomings would be the occasional noise from the restaurant right above and the heat that accumulates inside during this time of year (the windows aren't sufficient, in our opinion). Two fans are provided that help to some extent. Unless AC is provided, this seems to be the norm for anywhere in Rome (or Italy in general).
Regardless, communication was always prompt, friendly, and helpful, and we enjoyed our stay overall.
