Our family stayed in one of their family rooms, with a queen and a twin. Nice size room, good distance between the two beds, so there was a bit of separation, which was nice. Everything was clean and in good working condition.
Always lots of staff at the front desk, friendly, helpful, and very multi-lingual. If you only speak English, you'll do fine at this hotel.
The breakfast is also great. Simple, but fresh, and the lovely staff will get you a cappuccino (or two). Really good way to start your day.
Location is a bit outside of the 'thick of things', which we found nice. Very walkable, particularly close to the Colosseum and Termini station.
