Mixed feelings.
The location is top notch if you are interested in sightseeing. You will find yourself within walking distance from the most famous sights (Coliseum, Vatican etc.) Another benefit of location is that it has plenty of restaurants nearby. Expect lots of tourists around and noise, that didn't bother us too much though (windows do a good job of protecting you from the sounds ). Employees at the reception desk will provide you with the map with marked sights on it and give you some instructions on how to get there.
Now to the cons. Our room looked worse than it was in the pictures. It really could use some renovation. Don't get me wrong, it wasn't a disaster but we didn't feel like we want to stay in that room for a long time or spend there a day resting. Another letdown was the shower because it was literally leaking on the floor and you can't really call it a minor leak. We had to keep a towel on the floor all the time to deal with the water flowing out. Comforter didn't have a duvet cover, it was put in between two bedsheets (like a sandwich), we found that weird. Room was generally clean but sometimes you could see something like a thick layer of rust (?) under the brim of the toilet.
We had a short stay in Rome during which we were out sightseeing most of the time. If that's your case this room/hotel is an OK option to be your sleeping spot. If you are planning on staying for longer period (i.e. week) I'd look for something else.
