I highly recommend this place. Since the beginning my stay was great. Gian Marco was always open to help and answer any questions I had.
The check-in was super smooth and he even let me do it very early in the morning.
The location of the apartment can't be better, since there is a great nightlife on the surroundings and less than 10 mins away by foot of the historic area.
Unfortunately I had to leave the city before I planned but if I come back to Palermo I will choose Gian Marco's place again.
