Carlos place is super clean, has a good location in the city and it appears how it‘s shown in the pictures. From the appartement all the things to see were easily accessible by foot and hanging around for some time was also very comfortable. Also the kitchen has everything you need for a quiet evening with some homecooked dinner.
During our stay there was roadwork in front of the house (we knew that before) and some noise of course but that did not really bother us since we were out exploring the surroundings.
Only thing we want to give future travellers some hands up: palermo has a crazy parking and traffic situation! We were arriving by car since Palermo was only a stopover on our trip through Sicily. So if you decide to arrive by car, around the appartement there are blue lined parking zones which cost 1€/hour, lots of non-parking zones (where your car will be towed) and only few free parking spots where you can leave the rental car without fearing any damage. We found such spots with Carlos advise and in 10min walking distance from the place. Just keep in mind there is not really any possibility to leave the car in front of the appartement without paying.
