Laura and Marianna's place is great! The location is good and almost anything in the city center of Catania is within walking distance. There are a couple of bars and stores with extended hours near the apartment. During our stay, the elevator was out of order and as it's an old building and it was added later I can see it not working regularly. The floors are with high ceilings. :D
In terms of parking - there are some free parking streets near the apartment but you can use the 'blue lines' parking for approximately 5 EUR a day but the payments are weird.
The only thing we didn't exactly like was that we had to pay the cleaning fee of 40 EUR cash on check-in.
