We stayed at this hotel for one night with my mother in November 2004.

Good things first: cheap (55 euro for a double room), close to Termini and reasonably clean room.

Bad things: inconvenient small room and bathroom, awkward layout (reception on the second floor, rooms on the 4th floor, noise from the crridor when other guest come/leave, unpleasant reception).

Conclusion: the hotel is an acceptable budget option for one night stay, I would not recommend it for longer stays.

The Hotel office is 32 steps up, on the "first floor." There is a small elevator which can be used. The rooms are on the fourth floor, which is 108 (five-inch) steps above street level. The elevator will take you there.
We were in a quad-person room, overlooking Principe Amedeo street. It was very noisy with the windows open, and mildly noisy with the windows closed.
There was a small bathroom, with one towel rack. The shower consisted of shower pipes in the corner of the bathroom, with a curtain composing the other two walls of the shower.
There was no soap dish in the shower.
The towels were unique, like linen, rather than terrycloth.
There was one five-by-five inch washcloth for the four of us.
The soap was typical cheap-hotel-soap which barely lathered and seemd to leave a film on your face.
The bed was hard. I didn't sleep well.
The pillow was hard, and flat, even after I bent it double.
The staff was friendly and helpful.
Breakfast was not included, but was five Euros if you wanted to pay for it.
We got bread from a local bakery and croissants from the Bontempi Bar on Farini Street for breakfast. There is a fruit stand two blocks away by the train station where you can buy fruit.
There are numerous pizzerias, ristorantes and trattorias in the area. There is a McDonalds and a PastOrita by the train station.
It was amusing to this American to find the Italian Chinatown two blocks away. I can barely read Italian, much less Chinese Italian.
It wasn't the greatest place, but it was tolerable, if you don't mind a bit of street noise at night. It was actually entertaining to hang out the window and watch the action down below.
It isn't the type of place you stay for the hotel experience. It is the type of place you come back to at night for some sleep before hitting more sights early the next day.
I would stay there again. I'm not very picky.
My wife gave it two stars out of five stars.
My adult children gave it three stars out of five stars.
For you Internet addicts, there is a high-speed Internet point two doors down which charges one Euro for 30 minutes. It really was a fast connection.
The hotel itself has an Internet point for one Euro per hour, but it looks a bit old. I didn't try it.
The location of the hotel by the train station is good. The bus station is there. The Metro (subway) station is there. You can get to anywhere in Rome any way from the train station area.

Do not book there, unless you agree on paying 130 eur a night for a 2 stars hotel (no breakfast, basic furniture and ugly decoration), and not sleep the whole night !

The rooms are VERY basic, the showers designed in such a way that you end up transforming the whole bathroom into a pool when you shower, the towels are a joke, and it is the noisiest hotel I have ever experienced (we could hear people getting in and out the whole night, the reception guy was watching loud tv... ) We asked to change room, and after many discussions, the reception guy agreed on showing us another room with an atrocious smell coming from the bathroom.
We were relieved to leave, and never get back there again.

For the price (70 euro a night) rooms are modern, with enough space to move around.

Tiled floors, nice ensuite, but the smallest towels I have ever seen!! Seriously in Australia we call this size/ fabric teatowls (as in for drying your dishes).

No breakfast included, but no problems as we were never up that early. Great local food & coffee.

Ferrarese is walking distance to everything!! Would recommend.
