First off, we cannot say enough kind things about Giovanna. She is incredibly willing to help and give a wonderful time to her guests. She gave us some special treatment once she found out we were on our honeymoon, also. The apartment is much better than expected, actually. There is a ton of natural light and space to relax besides just the bed. The location was great for accessing buses and the train station so we could explore the landmarks of Catania and other Sicilian cities. It's walking distance to plenty of bars & restaurants, too. Many of which, Giovanna mapped out for us when we arrived. The bed, even though it's two beds together, was very comfortable! The shower was nice, and we never had a hot water problem. The WiFi was also very strong - we worked online for three days during our trip. There is no elevator, but the stairwell is wide and there are not many steps!
I would highly recommend staying at Giovanna's place if you want to have an easy and pleasant stay in Catania with a lovely host.
