Alessandro's apartment is great - very centrally located (2 minutes walk from the Quattro Canti), very clean and spacious. Beds are very comfortable (not a usual thing in the AirBnB places!), rooms are very tastefully decorated with little local details (pictures of the Palermo sights) and you can have a cup of coffee in the morning :-)
Alessandro is the best host you can imagine - very caring, friendly and communicative. He recommended us a lot of places to see and eat (Ferro di Cavallo is the one that must be mentioned here). We felt like home at Alessandro's apartment and hope to be back :-) It is a highly recommended place - no wonder Alessandro is a superhost :-)
