We spent three nights in one of their standard (no view) rooms, and loved it. Small and quiet, but with staff that were very helpful and friendly. Well positioned for the evening stroll down the Corso Umberto, and the views from the breakfast terrace really are stunning. Our room was very clean and had air conditioning.
I wouldn't hesitate to return. The only downside I can think of is that the nearest parking is at the public carpark at Porta Catania; while it's a short uphill walk, it is very difficult to park near the hotel and drop off luggage.
