The communication with Alberto was very easy. We were picked up by a nice lady who showed us the apartment. Also, Alberto was so kind to give us plenty of information on Palermo beforehand. The apartment itself is located in a lovely and reasonable student neighborhood, though we did not find it too noisy to sleep at night. Of course, the apartments unique selling point is the huge and wonderful rooftop. The indoor equipment is functional though very basic and missing some stuff like soap and clothes, the a/c does not work properly and is incredibly noisy.
Keeping in mind its affordability, in all we did enjoy our stay, good option if you are planning to be on the hop a lot anyways. 3,5/5
