We spent a week in the Green Apartment and really enjoyed it. We felt very much at home and didn't miss anything. The apartment is very spacious, the bedrooms are large and the bed was very comfortable. You can tell that Lorenzo put a lot of thought into the design, the furnishing and details of the apartment.
The apartment is in a perfect location and is very close to the city center and all the sites so you can walk everywhere. There's a nice little bakery down the street offering a good assortment of bread and rolls for breakfast and a supermarket next door to stock up on other things you might need. Other breakfast items such as botted water, juice, jam, some sweet pastries, and coffee and tea were already provided which is a very nice gesture.
Lorenzo provided us with some good restaurant tips. We can highly recommend the Gisira Pizzaria in Via Gisira which is just around a couple of corners from the apartment. It was so good that we went there 3 times during our stay. Very good pizzas, atmosphere and a true Italian experience. Other good restaurants were Fud (great burgers!) and the Polpetteria, famous for their meatballs.
There is traffic noise from the street so if you're noise sensitive, you might find this disturbing. We did mention this to Lorenzo and he said that he's looking at a way to reduce the noise level.
We can really recommend not only a visit to Catania but also to this wonderful apartment. Lorenzo is a great host and made sure that we had everything we needed during our stay.
