Federico’s place was fantastic! It is just outside the city center and 5 minutes walk to the metro/tram/bus stops. Very walkable and in a great neighborhood for visitors. Federico has a page of recommendations when you get in; take my advice to take his advice! We tried several of the restaurants & bars suggested and were VERY pleased! Lots of other options nearby as well. If you want more affordable and legit food, stay and eat in Ostiense.
