This is a fantastic flat in a fantastic location, which worked really well for our family of four. The flat is in a lovely block, overlooking a quiet and pretty courtyard, so we had no trouble sleeping, and the facilities are great: wi-fi, shower, comfortable beds to name but the most important to us! There is a children's park opposite, two supermarkets within spitting distance, not to mention great restaurants and a post office.
Sonia and Laura were great hosts. They responded promptly to our questions from the start, and left us detailed information about the local area, which helped us to find wonderful places like Testaccio market and the pizzeria Da Remo next door (which was well worth queuing for). Public transport connections into Central Rome from Testaccio are brilliant, and being able to live there for five days made us feel like honorary Romans.
I can't praise this apartment or our hosts enough.
