Perfectly located appartement in the city centre with all amenities you need even for a longer stay (I stayed two weeks). The King-Size bed was comfortable and a/c (heating this time;-) and internet working just fine.
Please keep in mind , that there are no windows besides the opening in main door and door to the back terrace. So because of this and the location in city center, don't expect any view.
But again, it's the appliances of the the apartment and the location of the in connection with the super service which makes this a perfect choice. Ask the Optima team for tours, trips, recommendations , they offer a lot!
If you come by car, ask for and that the parking service next door. Trust the Italian way and let the service guys park your (hopefully small) car.
To sum it up: Great value for the price and I will for sure check the availability of this appartement on my next trip to Catania
