Innocenzo's apartment is a charming and, I imagine, traditional Sicilian family-style apartment, very spacious, with inter-connecting rooms and period dark-wood furnishings. Bedding is comfortable without being luxurious and there is everything you would need for basic cooking, plus a table in the kitchen and a separate dining room.
The rooms are not brightly lit and would be shaded and cool in summer. In late-May one side of the apartment (a bedroom and the sitting room) allows morning sun. The other side opens (with high narrow windows and inner and outer wooden shutters) onto a light well and the next-door family apartment building. The local feel of neighbourhood life is nice (with children's washing strung on outside lines, etc, in the light well) and the quiet evening singing from a neighbourhood prayer room or mosque a few doors away is good to hear.
The location (minutes' walk from Palermo's central railway station and main bus terminal) is slightly problematic for late-night walking. Late comers need to be very away of the general problems of the city in this respect. However, the closeness to the station and buses is fabulous for trips out of the city (to the many wonderful historic and archaeological sites an hour or two out of town) and there is also an excellent free bus service that stops at the station and tours through the city and back streets, operating about every 10 minutes, all day, and running until about 9pm.
With its several rooms and two bathrooms, Innocenzo's apartment would be great for groups of friends in particular. As a pair of mature, well-travelled women, we enjoyed our stay, sometimes walking home (and keeping alert) at night from the centre of the city, otherwise eating a lovely main meal at about 4pm and bringing home good cheese and bread, etc, for a later supper. The truly fabulous Ballarò market is a few minutes' walk from the apartment, open all day every day, with great fresh seafood, fruit, vegetable, butchers' shops, cheeses and nearby bakeries.
