We booked at the same day as we arrived in Palermo. Vincenzo answered very quickly and the communication was quite easy.
We could park our car for free right in front of the house although the street is quite busy. The house is quite good located. You can easily walk to the main train station. The city center is also walkable.
The flat itself was a bit noisy. You could hear anything through the walls, even the elevator (our room was next to it).
Vincenzo provided a simple but good breakfast. All in all the price was suitable for what we got.
