We stayed 4 nights at Ester and Salvo's place and had a great time. The apartment has everything you might need, coffee machine, microwave, plates, cups, utensils, etc.
It's spacious, bright and modern. The bed is comfortable, the showers have amazing water pressure.
If you are a light sleeper, you might get bothered by the restaurant noise from right below the apartment, but the host provided us earplugs and we were so tired by the end of the day, we couldn't care less.
It is at a great location, all the major sights are an easy walking distance.
Catania is a good central location to all of the other touristy cities, Taormina, Syracuse, Noto, Agrigento and so many more.
