Check in was very easy. Ester was very good at communicating to us while we found our way. Flat easy to find as major square in catania. The flat is very central but also slightly away from the main square so it feel nice to walk home from the main centre bustle. Your view is directly across from the castle so very atmospheric and we enjoyed sitting on the balcony watching the world and the Italian baptisms celebrations. Piazza federico however ilt is still a city Square so you need to want to get the city vibe. It us not a quiet side street. Need to close window at night but air con very good. The flat is well equipped and we were able to make a nice meal on the times we didn't use the lovely restaurants. Flat has useful guides and map which we used to get around as well as google. All sites very near. Area very safe. Short stay as we were touring but would come back. They went out of our way to help us so very friendly people. Enjoy your own visits to lovely catania.
