I spent only one night there but it was a pleasant stay. When we met, it appeared that the room I booked is already taken and I was offered another room with compensation. Another room was a bit smaller but it was ok for me and I agreed.
The room was clean and fresh, the bed was very comfy as well. I was also provided with a bottle of water and a ticket to a caffee nearby for a free coffee and a croissant which were very tasty.
The location is great as for me: 40 minutes to Fumicino airport, the same amount of time (but walking) to the city center. There was also a very nice route for running along the Tibre nearby as well.
But keep in mind that it located near to the train station so if you have a bad sleep this can be the problem for you.
