After pointing our travel agent to this hotel based on other TripAdvisor reviews, I have to say we weren't disappointed with this hotel at all. The location, two short blocks from the Roma Termini station, makes it very convenient to hop the Metro or bus to visit any location in the city.
The rooms were on the smallish side, but our family of four were not interested in anything but a place to sleep and get cleaned up. The main bed were twins stuck together, with two cots on the outer edges of the room for our kids. All of the mattresses were firm, and comfortable. The air conditioning worked well, and our room had a window that could easily open and let fresh air in.
Americans who don't travel to Europe much might be thrown off by the lack of shower curtain in the bathroom, or the fact that there doesn't seem to be washcloths in Italy. But we don't blame the hotel; this is a cultural thing.
The breakfast was typically Italian continental and decent. The staff was helpful, but sometimes a little too busy to answer questions in detail.
Bonus features: there's a laundromat (not self-service) around the corner from this hotel, and try the Trattatoria Gemma alla Lupa around the other corner. It's cash only, but the quattro frommage pizza is excellent.
If we visit Rome again, we will stay here.
