I am a solo traveler and spent two nights at the Ritz as part of a tour group.

The room was more like a cell! The bed was so close to the wardrobe that the latter could not really be used. The brocade wallpaper and drapes were overpowering and added to the gloom of the poor lighting.
There was NO additional furniture (e.g. table and chair) and the only place where I could write some notes was on the toilet.

The air conditioning plant was just outside my window and it roared on all night!

The location is NOT central and there is not much in the way of restaurants nearby (although the pasta place just down the road was good)

I am sure you can do better. I would not recommend this hotel and would not use it again.

My wife and I stayed here on August 30 for one night prior to a cruise. The hotel was selected as part of the cruise booking so we did not know much about the hotel or location until we arrived. The hotel seems to be located in an urban residential area. Our third floor, street side room included a sitting room, bedroom, and bathroom. The tub/shower had the half-glass arrangement that others have mentioned and not a full shower curtain.

The staff was professional and helpful to us non-italian speaking guests. The buffet breakfast was quite complete - a wide selection of hot and cold foods. The coffee was fine.

English speaking TV channels were limited to CNN international and BBC international. Wireless computer access was allegedly available but I thought it to be too expensive to try out.

We went out the hotel front door to the left, turned left at the corner, and went a block to the Euclide subway station. For one euro each and two subway stops, we popped out at the Flaminio subway station which is nearby the Piazza del Popolo, a touristy type area with plenty to see. (The subway ride was borderline unbearably hot.)

We found a nearby grocery store with assistance from the front desk . We bought wine, cheese, bread, and meat for a meal instead of forging out someplace and spending a lot of money on dinner.

You can look at Google (satellite view) to get an idea of what is around all these spots).

Bottom line, the hotel and location were a new experience for us and perfectly satisfactory.

The staff are unfriendly, unhelpful and look like they hate their lives. Our bed-spread had a cigarette butt on it and the faulty shower went from hot to cold. It's a far distance from the centre and we had to get taxis when the train stopped. When we asked could if we extend our stay, they couldn't have given a toss either way and treated us like we were a terrible burden to their already miserable existances. When they said we couldn't stay, we didn't mind and paid extra to get out of there into a more expensive place.
On the positive side, the breakfast was varied and sufficient, even if the coffee and juice was machine operated.
It will dampen your stay at Rome if you stay here. It did ours.

We spent four nights in this hotel as part of a Riveria trip.

Our room was lovely, spacious, clean and a large bathroom.

Breakfasts were poor, how can Italians serve up grey coffee? And tinned fruit in a country bursting with fresh was an insult.

Some staff were really good and others, particularly the male manager, couldn't raise a smile.

Certainly not 'centrally located' as promised by Riveria, few eating places close by, so wouldn't recommend it.
