We spent four nights here and it was ok.
Room is located close to main bus station and train station and quite close to the city historical center , which is great.
Bring on some earplugs if you are not a heavy sleeper.
Switch your mobile to some other network than VodafoneIT or you might have some signal issues while inside, but we managed ok by leaving the mobile phone close to the door.
Catania seems rather safe during the day (we did not go out at past 7 so i can't tell you about nights)
Be careful as a pedestrian , drivers seem to be in a hurry.
I would gladly stay here again.
