Hello, we stayed in this apartment for 10 days, it is ok for 4 people.
Pluses:
-good location. 10 min to Сolosseum, 10 min to Termini railway station, 3 min to metro station
Minuses:
-problems with water pressure, and big problems with hot water - sometimes it was impossible to shower
- bad sound insulation, but i think it is common problem for all old buildings
