Katarzyna's apartment is a lovely place to stay in the middle of Palermo. Most of the main sights are within an easy 15-20 minute walk. The highlight of the apartment is the rooftop patio, which offers beautiful views of the city and surrounding mountains.
The apartment is located on a street with bars that remain busy deep into the night, but the bedrooms are positioned in such a way that they didn't cause us any problems sleeping. That said, if you are a light sleeper, it might be best to find a place that is not so centrally located.
The apartment was clean and well-appointed throughout, though the lack of natural light in the bathroom led to a few discolored spots in the shower. The listing also notes that shampoo was provided, but we ended up having to buy our own.
Check-in could have been a bit easier, as Katarzyna directed us to pick up the keys at a nearby bar without providing a precise address. She responded to our questions quickly, however, and we eventually found the right place.
Overall, this is a good apartment for spending some time in Palermo. It is an excellent value, even after considering some of the small problems we encountered. I recommend it!
