Nunzio and our other hosts were very kind, flexible, and kept up good communication. This apartment was only a block away from a bus stop with access to the CTA airport (Alibus), which was very convenient. It was also only a 30 minute walk (or an even quicker bus ride) to the train station so that we were able to visit other cities along the coast like Siracusa. We also bought a tour to visit Mount Etna for the day, for which there are many options that depart from Catania (ours left from Villa Bellini).
The park of the Villa Bellini just a few blocks away is really lovely as well. The apartment was very clean and comfortable for 3 people. My only suggestion is to bring earplugs if you are a light sleeper as there is a bit of noise at night from the cars passing by on the main street. Being located off of this main street did help us to feel safe walking back to the apartment, so it seemed a reasonable trade-off.
