I had heard some bad reviews after booking the hotel and so was quite apprehensive but I have to say, the hotel is nice. Okay, so it's not right in the centre of Rome but looking at some of the properties situated there, that was a god-send! The staff were friendly, bi-lingual (speaking up to four different languages) and very helpful.
There were tours bookable from the reception whereby you were picked up from the hotel and transported to the coach company who did the tours. There were some very reasonable prices - the one me and my sister did was 35 euros each and it took you around ancient rome - the roman forums, the colleseum, etc etc. Definitely worth while, especially as you get transported back to your hotel at the end of it and would be cheaper than getting taxis around the different places and getting your souvenirs.
The only downfall I have to say with the hotel was the lack of privacy due to the thin walls. I could hear people taking showers next door and often you could hear people mumbling when talking and laughing also. Its ok if you want your hotel to be a base for sleeping and eating (they have a nice restaurant - fairly priced italian cuisine) but I wouldn't recommend to those of you who want to be central or who don't like any noise or disturbance.

Read very varied reports about it and were a bit uncertain. Pleasantly surprised. It was clean, rooms ok with airconditioning, food ok (we only had breakfast but could fill up for the day!), swimming pool was clean. Staff were very helpful + pleasant.
A lot of comments stating how far it was from the Vatican + central Rome but taxi was fairly cheap + the Metro was quick + efficient. The nearest metro station is about 15 mins walk but if you buy your ticket (small shop behind the first petrol station you see) this includes bus travel to metro (only about 3 stops).
We found it a cheap alternative to the city centre hotels + was fine.

I stayed in this hotel for 2 nights as part of a package tour to Rome this month. Facilities were clean and comfortable, not at all like I was led to believe by the reviews I read on this website. What more do you need? Rome is busy and exhausting, so there was no problem sleeping, and if all you need the room for is a place to shower and sleep, as long as cleanliness and comfort are there, the rest doesn't matter. Breakfast was adequate, and we were able to take enough from the buffet table to make a picnic lunch. This is a clean, decent hotel, at reasonable rates. You will pay much more closer to the centre.

Ah Italian hotels...I don't know what rating system they use, but this is definitely not what most people would call a 4-star hotel. It is basically a big boxy hotel designed for tour groups. To be fair, I have stayed in much worse and for its purpose, I think it is fine. However, if you are the average tourist on your own, I would not choose to stay here.
First of all, rooms are tiny - however they DO have air conditioning, which is great. Bathrooms were also small and the provided "towels" were more like dishcloths. The tv screen was smaller than my laptop with only CNN (in black and white) for non-Italian speakers to watch. It appeared that some rooms had renovations and used key cards, while others were older and were still using keys, but I don't know if there were any other differences. Another big complaint - the walls were paper thin. I was staying with colleagues who were in the room next door and we could literally have conversations through the walls at normal speaking volume. The breakfast was blah..just dried up croissants, water, stale cereal and juice.
As for access to city center Rome without a tour bus, you can either walk to the subway in about 20 minutes along a busy road or take taxis. It was about 13 euros by Taxi from Piazza Navona, which isn't too bad if you are sharing.
If you are traveling on your own, stay somewhere else. If you are taking a tour and are being put up here, it's not going to be luxury, but it's not terrible and at least you aren't stuck an hour outside of Rome.
