We stayed at Antonio's apartment for four days and it was perfect! Antonio and his mom were kind, welcoming and helpful. The apartment is ideally located in Palermo near many fantastic cultural sites, shops, cafes and restaurants. La Martorana, Teatro Massimo and the Cathedral of Palermo all are within walking distance. We also took a day trip to Mondello beach which was lovely.
As for the apartment, there was more than enough room for the two of us. There is a balcony off the dining room and a gorgeous patio on the second floor. After a long day of exploring the city it was great to be able to relax up there with a few beers. The AC cools the apartment quickly, the washer works well and if you decide to rent a car there is ample and free parking across the street.
Highest recommendation possible! If you're traveling to Palermo then stay here!
