lest start with the cons - this is 3rd floor, no lift, and it sometimes feels like 5th floor after a long day :) so i would not recommend to anyone with any moving disability. Secondly this is in the centre - so it means you can hear the Catania party going on during the night :) which adds to the experience, but if you expect very quiet surroundings i would not recommend it either.
now the pros - the terrace view is truly fantastic and it makes it worth the climb to (another floor up), the place is spacious, clean, well furnished, you have a lot of extra space (balcony is great as well) and lot of privacy. the location is amazing, just a quick walk to fish market, bars, cafes, plenty of interesting things around, makes really for a great spot for visiting Catania. The communication with host was quick and problem free. If we ever come back to Catania (I hope so) I already know where i would want to stay :)
