We really liked Mirta's apartment. It's like a small hostel after there were some other guests in the apartment as well. The rooms were clean and the kitchen could be used to prepare small things (without cooking). The apartment is not central, but has got a perfect connection with bus and tram to the city (15 min with bus to vatican city; 20 min with tram to piazza venecia). Mirta was very nice and helped us with bus and tram.
Very Nice!
