Stayed for 3 nights this summer in an 8 bed dorm, there are much worse places but i'm sure you could find better.
The place was pretty clean and modern, and they give you free pasta during the week which is useful.
The rooms are quite big and uncrowded but get very hot during the summer, which is not helped by them padlocking the window shutters, making the rooms very stuffy.
Their was no hot water on out floor for the entire time we were there, no effort was made to fix the problem they just told you to go upstairs.
The main problem we had occured when on the last night the the hostel informed us there was a train strike planned. After talking to them the next day we were persuaded there was no way of getting out and so had to book another night. Later we learnt this was completly untrue and left - however even though we didnt need our beds no refund at all was given. Basically from this we learnt they are trying to get your money, and once they get it they don't care.

Overall it was ok, but our time in Rome was ruined a bit by their useless info and staff. The prices are a bit of a rip off and i'm sure you could find better, cheaper in Rome

Service:
Friendly, helpful staff. On arrival a woman gave us a street map of Rome and explained the easiest ways to reach all the top sites, recommending restaurants to us and directing us towards the areas for young people at night during the summer months.
One of the girls I was travelling with left some documents and traveller's cheques behind which the hostel posted on to us at no cost.

Location:
Very close to Termini station. Easy to find and not a long walk with your heavy backpacks. However, I wouldn't have felt safe walking alone at night here (being a young female).
Easy to reach colosseum/vatican/other sites.

Rooms:
Largest rooms we stayed in during our trip around Italy. Never felt crowded despite being an 8 bed dorm. Clean, modern style. Space to hang up towels/some clothing. Lockers in the rooms.
TV room with ok selection of dvds.
Breakfast was fine - selection of cereals, bread rolls, tea/coffee/juice.

Would stay there again.

We stayed in this hostel recently for three nights. The hostel is in a good location if you are coming in by train as it is 5 minutes from Termino station.

The first thing you are faced with is a 69 step climb up to the hostel although there is a lift it is claimed the lift is faulty...

The people at the front desk seemed friendly enough and theygive you a map of Rome which came in very handy.

The rooms themslves are boiling hot, no air conditioning. There is a fan but it didnt make a blind bit of difference in the stifling Rome heat. The covers on the bedding were filthy so i slept in my sleeping bag sheet.

The bathrooms well there is one with three showers and three toilets one for men and one for women and i never managed to get in the shower on the first attempt it was always busy.

The breakfast served was adequate, it was rolls, juice and cereal which is better than some hostels i have stayed in.

I would recommend you dont stay here if you do not like sleeping in the boiling heat.

All in all, an ok place, though the kitchen and internet facilities didn't seem to be enough for everyone, and my bed squeaked terrrribly! Room was spacious. The elevator didn't work and it's up a couple flights of stairs.
