The apartment is comfortable for 4, maybe 5 people. It is fully equipped with everything a house can have. I stayed there for 5 nights with my wife, sister-in-law and my 4-year old son. We cooked every night and the kitchen is excellent if you are also planning to cook some meals at home. There are supermarkets and all sorts of stores only a few meters from the apartment.
We had lunch, a couple of times, at a bar called Tahiti, also near the apartment, excellent food and price.
Dario and Laura are great hosts and helped with some details of our trip.
I would definitely stay here again when visiting Rome.
Thanks for everything.
