Our room was located in what was essentially a converted portable of sorts. The entrance was a floor-to-ceiling glass patio door set which provided no privacy unless the blackout curtains were pulled, at which point no natural light entered the room. The shower stall had painted walls (not tiled), with mold in multiple locations. The beds had thin, spring mattresses that were uneven and uncomfortable. One pillow had stains. To be fair, it's possible the experience would have been different if our room had been in the main hotel building. Note as well that the shuttle service did not run hourly which may or may not be a problem for you.
Now the good. The hotel is only a short ride from the airport and the neighborhood contains a very safe and walkable street running alongside a branch of the Tiber river with numerous restaurants covering almost every type of food that you could want.
