As others have noted, the location -- everything from its site just off of charming Via dei Coronari, to its proximity to Piazza Novona, as well as many points of interest within easy walking distance (Pantheon, etc.) -- is close to ideal for most visitors to Rome. And the rates can make this an exceptional value. I stayed from Nov. 1-6. But note: I was given what apparently was an extremely low rate (by a wonderful, extremely helpful day clerk, whose name I think was something like Giorgio) when I walked in off the street seeking a room for 5 nights. But when I inquired of a different clerk who happened to be staffing the desk another day, about the rate for a room for my wife, who would be looking for a room just as I would be departing, I was initially quoted a much higher rate -- 180 euro for the first night, and 150 for subsequent nights -- than the one I was paying. Later, when Giorgio returned, he agreed to give my wife the same very low rate as I had. So although tte rates presumably vary according to the time of the year and how booked they are, they also apparently vary (at least when you're talking to them in person) accordng to who you deal with, and it may be advisable to try and negotiate a bit. I was in room 301, and had no problems with noise (but maybe that's partially attributable to being generally insensitive to modest street noise). During the day -- but not night -- there are church bells which sound regularly, but I found those to be charming, rather than a shortcoming.

Giorgio?

The room was clean with a nice and comfortable standard interior. The hotel has truly one of the best central yet very quiet locations in Rome. Absolutely recommendable, very good price/ quality ratio. Plus: very friendly staff. Thanks Michael for the nice chats, and Daniel for the helpful advices.

We received a very warm reception which was nice. Daniel (I believe his name was) was extremely helpful about the city and providing maps etc. We also spoke to a few other staff during our stay about attractions etc and we found them very helpful.

The room was lovely, clean and very large. The only downside was the noise from the people living above our room as you could constantly hearing them moving around.

We found Rome was easily walkable and we were able to walk from the hotel to the Colosseum, Vatican, Trevi Fountain etc without any problem (except the heat!). The hotel is very close to Piazza Navona for dinner if you are happy to pay the expensive prices otherwise there are many restaurants close by.

Tip: You must try the gelato at the shop very close by - the best in Italy by far!!

Very small and dark room, but clean and adequate. Considering the location (which was great) and the reasonable price by Rome standards, you can't expect perfection.

Breakfast was decent, and served in the room. However, it would have been nice if there was somewhere proper to sit and eat as it was rather awkward to eat sitting at the foot of the bed.

Noise carried a fair bit between the rooms and the street noise was quite loud at times.
