Great hotel, clean, breakfast ok, mattress not very comfortable, but I think that's very common in Italy, little far from attractions, but walkable and there's a tramway in front of the hotel that takes you to Termini. Colliseum is about 10 min walk, subway is about 5 min. Hotel area is not very friendly, graffiti and dirty, but we felt safe, no problems, plus we didn't have problems with noise, so it was a trade, other hotels we checked seemed to be very noisy.
Staff was very professional and pleasant, they offered us to keep our luggage after check-out, so we could enjoy Rome a bit longer before our flight, we appreciated our stay.
