The house is comfortable and cozy. It's very spacious and has good furniture. The garden is a bit bland, but there appears to be a grill, although we did not use it.
The fireplace is very nice, but you have to buy your own wood after the first load. They provide different options for that (not expensive).
The central heating works, but do not expect the whole house to get really warm. Bring slippers for your feet.
The location is not great. It's a calm neighborhood with residential buildings only. There is a supermarket about ten minutes away by foot. There are no sidewalks to walk on. With traffic, it takes a good 45 minutes or longer to drive to Catania center. Pretty much every attraction is at least an hour of driving to get anywhere nice like Taormina, Caltagirone, or Syracuse.
We had some trouble opening the garden gate, which took a fair amount of rattling to unlock sometimes, so we just left it slightly open.
The "breakfast included" was not nearly enough. Some biscottos with a liter of milk (one biscotto per day haha). And an already opened pack of chocolate cereal (maybe a previous tenant left that). So do not expect a breakfast except for the little coffee machine.
The mountain view is not the Etna, but a smaller hill.
