Pros:
We were checked in by Simone (who is a hired greeter by the company who owns this Airbnb). He was friendly and informative. He gave us a thorough run down on how to get around the city, gave us a map and tip/recommendations.
The location was good. We were so close to Rome Termini station which was perfect for us. The place was clean and the building had an elevator.
Cons:
The pictures are not accurate. The floor of the place is completely cracked and torn up. There was duct tape on the floor. The paint on the walls was peeling in the shower. The bathroom sink drained so slow that we used the kitchen sink for hand-washing and brushing our teeth. The toilet was not pleasant to use because every time you would sit down the seat would move. I excepted so much better and for the place to at least look like the pictures.
