I stayed one night at this hotel during a trip for work. The location is pretty good. My single room was on the small side, but clean, comfortable and nice enough really. The bathroom was a bit awkward (very cramped), but also clean and functional. The reception staff were very nice, friendly and helpful. Not sure about value for money as i don't know what was paid for the room, but would be happy to stay there again.

Hotel Traiano was clean, with courteous staff. Room was small but clean, bathroom well groomed. My room (2 nights) was on the street but not too noisy with the windows closed. Usual continental breakfast, good quality (no hot foods though). Center of the action to sight-seeing, easy to walk to all major sites and the shopping district. Knowing what I know now, I'd likely stay out of Rome center and take excellent public transport trains into the center of action. Local restaurants were way over-priced, under-portioned and not very tasty...I ate much better after I left city-center...Overall OK for a first time visitor, but you can probably find cheaper yet just as accessible a little ways out...

Spent a couple nights there on business.
As mentioned in other reviews the location is great - near the major sights.
I must have been a bit unlucky as my room was small and unfortunately opened onto the main road which turned out to be a nightmare. I practically felt like I was sleeping on the sidewalk. Extremely noisy. However I was only there for a couple nights.
The room was small as mentioned but clean.
Breakfast was Ok with the usual cold cuts, yogurt, cereals, etc.
The hotel is a bit aged but not really an issue. The front desk was courteous and helpful.
All in all OK for a couple nights - just try to get a room internally.
