This is a b&b. Room is exactly as pictured. It has your own bathroom, mini fridge and balcony with big windows. Bed is very comfortable. The location is very convenient, right next to Termini, 30mins to airport FCO by Leonardo Express.
Note that there's a €3.5/night city tax charge? I'm not sure what that is, but you have to pay by cash on arrival.
You get a free breakfast with a bar close by. I didn't go take it so I can't tell the quality.
