I'm quite satisfied with my stay in this hotel, even though I have some critics too, but they are more about the neighborhood than about the hotel.
The hotel is not big (actually occupies the second floor in a building).
The first thing you need to know is that you shouldn't look for a big sign, but for a small plate by the door. The second warning is about the reception working hours, which are only 6-21. So for late arrivals or extremely early check-outs you might have some problems.
Apart from that, everything in the rooms looks and feels good, breakfast is nice for Italy and a 3-star property, and the service is the best of all - including the English everybody there speaks.
The good things... Free breakfast, free and fast wifi, very convenient location, just meters from one of the stops of the airport bus (named Alibus). Walking distance to the historic center (less than 1 km, via one of the main shopping streets in Catania).
The not so good... At first the area doesn't look very well - not too clean, with a lot of street vendors around, mostly African migrants, but actually they proved to present no security risk whatsoever - and there is enough police everywhere. Also the distance to the extraurban bus and train stations is 1.2 km and one day there will be metro to there, but it's not working yet - and because Google knows nothing about the local transport options, you'll most probably have to walk.
