The organization of the stay was alright. However, there are some things you should know about the place:
Location:
The area is conveniently located next to tram and bus lines, but also next to rail tracks. It's not quiet in the night. Main sources of noise are trains, police, and the refrigerator. Also, there is an apartment just next to it with thin walls, so chances are you're gonna overhear your neighbors too.
Amenities:
Here, essentials means towels and linen, but not shower gel and shampoo. Make sure to bring your own shower utensils when you come here.
Equipment:
The beds are very comfortable (rather hard mattresses, that's what we liked). The shower is the tiniest I have ever seen in my whole life (and this wasn't my first time in Rome!). The kitchen is inside the living room, if someone sleeps there, you might consider not to cook odorous dishes there.
Communication:
The administrator Francesco is very cordial and a kind-hearted person. The owners live in Brazil and their communication consisted of standard copy-and-paste messages. Although I had given some information already in my introductory message, they didn't seem to have read it and asked the same information again in one of their messages. This is why I missed the warm, welcoming experience that airbnb usually is to me.
Value for money:
In my opinion, the apartment is not exactly cheap for what you get. If I come to Rome another time, I would not stay here again.
