TL;DR: Great apartment with a functioning kitchen and nice little balcony, central location, quiet considering the location
Great little apartment in a very central location! The area itself is very touristy, but it's also a short walk away from most attractions in both the old and new parts of the city, so a perfect hub for seeing Palermo. There was some noise from mopeds, restaurants carting away trash and construction that was going on close by, but surprisingly little considering how close the apartment was to the hustle and bustle of Via Maqueda. I don't recall noise from outside interfering with my sleep a single time in our two-week stay.
The little balcony was perfect for having breakfast before heading out or for late night drinks looking at the picturesque alley the apartment's located on. Kitchen was also nice, though it was not stocked aside from coffee and single-serving bags of salt and sugar when we arrived. Possibly for covid-related reasons, who knows. Luckily there's a Sisa supermarket close by.
Bathroom was clean and included a washing machine, which is a nice bonus. There's limited hot water in the boiler, but it was never really an issue with two people taking showers in the morning. Air conditioner was also nice, although in late November it wasn't as critical as it would have been in warmer months.
