I visited Rome together with my mother in November and stayed at the Raffaello Hotel. I booked 2 single rooms - one turned out to be quite small (#116) and the other was decent size (#510). I've stayed in this hotel before and really enjoyed my stay.
Our rooms were small but then again these were single rooms. Otherwise rooms were clean and comfortable. TV sets were LCD but VERY small. Bathrooms were good size, and water pressure was good. Free wi-fi and breakfast (very good one) was included. Service was great as well - very friendly and helpful.
Location is perfect: 10 min on foot away from the Coliseum and Forum, close to 2 metro stations and Termini, and close to many different restaurants and small convenience stores.
