Gizi's apartment was a joy for us to use for a week. We loved the balcony, the spaciousness, and Gizi's friendliness. Domenico at the reception to the building (M-F) is very helpful and speaks English.
The two bedrooms are bright in the daytime and the beds are comfortable. The kitchen is well equipped; we made and ate all of our meals in the apartment.
From the airport, the shared-taxi and the bus both stop 250m from Gizi's, on Via della Liberta at Notarbartolo. At the same location, several buses head downtown. It's very convenient.
The building is from the 1950s, and was likely luxurious in its time; however, some aspects have not aged well. Some guests may enjoy the charm and nostalgia, but those who prefer modern efficiency may find it less appealing. The elevators are old-school; certain areas of the apartment are dim at night, there are quirks with the electricity. We still loved our stay, but I mention them to be thorough.
