I've stayed here in November 2006 while my girlfriend was living in Rome. I was visiting her and caught a flight to Rome without any previous hotel booking. Hotels in Rome are extremely expensive, be aware. The cheaper ones are very difficult to find, all busy.
First time i was in Rome visiting my girlfriend i stayed at Cascina Palace, which is very far from the city and very bad!
This one (Adriatic) is a very good place to sleep in Rome, very central, and clean. Don't expect a luxury hotel, you won't find it here.
If you have small budget and want to something just to sleep in Rome, Adriatic is the right place for you, just near Vatican. I think i paid something like 30 euro per night, which is almost for free in Rome!

It is a typical European hotel. There is no breakfast, but there are plenty of places across the street. Great location and close to the major bus lines. Plenty of cheap places to eat just around the corner. The hotel was clean and staff very friendly.

we stayed for 4 nights in february 2008 and found the location of the hotel excellent,very near the vatican and easy access by bus.
The staff were all pleasant and very helpful.
The room and en suite was modern and cleaned daily.
Because of its location it can be noisy at night ,but I would still return again to this hotel .
There is no breakfast or drinks provided so my only suggestion would be take a travel kettle.

Stayed in Adriatic for 6 nights in October,hotel was clean,staff was very friendly and helpful.Bathroom was pretty small , but clean and renewed.Location! Location is fantastic , about 5 min walk to Vatican,5 min to St Angelo castle,20 min to piazza Navona.There is a little supermarket near the hotel - good prices.Want to recommend the cafe shop across the street (on the corner) - good cappuchino and not expensive.
