Great place. We stayed there for two nights.
The apartment is in a very nice and central location. Lots of nice restaurants around (e.g. La Rustica, where you find simple, typical and delicious dishes). You can walk downtown in 5-10 minutes and even to the beach in about 20 - 25 minutes.
We found a space to park exactly in front of the apartment.
The check-in was well organized. Marianna, a friend of Pierluca, welcomed us very friendly and explained everything.
The apartment looks exactly as in the pictures. The air-conditioning is perfect for Sicilian temperatures. Since you can hear the cars driving on the street, I used earplugs at night.
I recommend Pierluca's apartment for a simple and perfect trip to Catania.
