The host's representative (agent), Fabio, was very informative and helpful. He responded quickly with any issues.
The apartment was amazing, exactly as in the photos, 2 huge bedrooms, 2 huge bathrooms, a fantastic living/dining/kitchen area, tv's in each room, great wi-fi, washing machine (no iron though).
There is a lift to the 2nd floor apartment, and a huge park next door (I got lost on my run it is that big).
The nearby surroundings include cafes, restaurants, bakeries, supermarkets, and the metro is 5 minute walk, so handy. It took us 15 minutes to get to the colosseum.
We were very happy with this accommodation and would highly recommend it.
