The apartment is really cute and totally worth the money. We loved all the small details and the high walls. It has all the charm of an old apartment but is still modern and very clean. Everything we needed (coffee machine and coffee capsules, dish washer, soap, towels, oil/salt/pepper...). We really enjoyed to stay there.
Elise and her parents are excellent hosts and the communication was really good. We were even able to leave our luggage a bit longer as our flight was late in the evening. We really appreciated it.
Even though some people already mentioned the noise from the fish market (and music from bars in the evening/night) we were a bit surprised about how loud people can actually shout outside before 7am. In our opinion the bed was also too soft but I think that's a question of taste.
Nevertheless as the apartment is in the middle of the old town and everything is nearby one cannot expect to have a totally quiet place. That's why we would still love to come back one day and would totally recommend it to everybody who wants to see Catania and it's real (a bit loud) life.
