Great location and the flat was perfect for my fiancee and I.
The building is a majestic Palermo style building in the middle of the heart of the city. (Think Rivoli or Oxford street but in Palermo).
Still, it is very quiet. You enter through a wooden gate and instantly feel in another dimension. A quiet court leads you to the building entrance where you are welcomed by a doorman.
Alessandro greeted us and showed us all the facilities in the building (like a parking space and an elevator) and apartment (equiped little kitchen, huge bathroom, air conditionning and what we liked the best, the rooftop view on the theatre).
He also have us tips about restaurants and places to visit, which was really convenient.
So a really nice place to stay and we would recommend it at 100% to every Palermo lover.
