The Beehive is a perfect affordable hostel for a week long trip. The location is great being next to Termini station and there are some nice shops, restaurants and cafés surrounding it.
The building itself is secure and clean with well furbished rooms, a community kitchen and lounge and though it does have shared bathrooms one was always available when I needed it. Best of all, even after checking out they let me leave my luggage there for the day since I had an evening flight and due to their security I didnt need to worry about my bags being stolen while I was out. If I'm ever back in Rome, I'll be booking here again.
