This little two-story apartment was clean, cozy, and perfectly situated in Palermo's historical district, with easy access to the main streets, the sea, and endless shops, restaurants, and street vendors. It's tucked away in a little square and we always felt quite safe walking to and from the apartment, even in the evening. Paola was always quick to respond to any inquiry, and was over that day or the next when we needed help (though we didn't run into any major issues).
The only downside to the location is the club next door - most nights there was fairly loud music and crowd noises until about 2am, and the windows were only half decent at muffling the noise. We were happy to put up with this considering the central location, price, and quality of the AirBnB, but if you're a light sleeper it's something to consider.
That being said, it was easily 5 stars from us! If we ever revisit Palermo we'll look into staying here again :)
