Wonderful place to stay to visit this wonderful city. We visited with a family of 4.
The description on Airbnb is 100% correct. Nothing to add there. The apartment is large, comfortable and strategically located. Good internet. Comfortable beds.
Bus stops right in front of the apartment. Just a few minutes to the Vatican, and about 10 minutes to the center of town (Vittoriano/Plaza Venezia with bus 916). To get to the metro, take another quick bus rid.
A great pizza take-out food place is next to the building. All-you-can-eat Japanese food is 1 block (turn left, then turn left at the next street). And a few more restaurants in the vicinity. A (smallish) Coop supermarket is 2 minutes walking distance.
Alexandra very kindly arranged transport to/from the airport at a reasonable rate with a comfortable van. No sense in spending almost the same on train/bus with all the hassle that would have entailed.
Our 1-week stay was very pleasant. I recommend this apartment to anyone looking for a comfortable place, close to the center.
