This apartment is located on the top floor of an apartment right off one of the main streets. The location is great and everything is easily reachable from there. The train station is about 15-20 mins walking away and the next bus to go to the airport about 5 mins away. The self check-in was quick and easy and Antonio was responsive if we had any questions. We were allowed some flexibility during checkout, which was very much appreciated. The flat itself is large and has a balcony and two(!) terraces with nice views of the mountains. The furniture and fittings are a little bit old but except the red chair in the bedroom everything was in a working state. The bed was comfortable, 3/5. The bathroom and kitchen had a set of basic amenities that were sufficient for our stay. There is fast and reliable fiber Internet. However, there was no detergent for the washing machine, and after we bought some and washed some clothes we realized that there was no clothes drying rack to be found. Please note that the historic center is brimming with activity and no matter where you are there will be some noises from bars, markets, vendors, etc. In the case of this flat this is less of an issue due to it being located so high, however as others have pointed out there is a place down the street that plays loud dance music during the night on the weekends until about 3am. With the blinds and windows fully closed it was still noticeable but fine for us (I had way worse). If you are a light sleeper you might want to pack some earplugs for those periods though.
Overall, this is a very nice flat with great views at a great location with some minor downsides which are made up by the great price. I will definitely look into booking this place again when visiting Palermo next time!
