Federico provided a clean and safe home, away from home!
While not directly in the city centre, his apartment was less than 100m (easy walking with large suitcases for 2 young females) down the road from the Manzoni Metro Station on the A-Line (2 stops from the main station + same line to get you to the Spanish steps/Trevi fountain!) .

Lockable private room, with shared (clean!) bathroom. Very safe building, safe neighbourhood and food very close-by if feeling lazy in the mornings/late at night.

Wifi worked well, and Federico was available to make suggestions regarding places to visit/eat, though we tended to only cross paths once a day.
