Massimo's place is amazing! The apartment is cute and cozy, a on the smaller side but very comfortable for two people. The bed is comfy and the shower is good and hot. All the tools you need in the kitchen are provided, along with coffee, some spices, and a few treats.
I'd say the best place about the apartment is the location -- when you walk out of the building in the morning you are basically in the middle of the market. You could buy ingredients for a day's meals for under 10 euro, or if you want to go out there are quite a few restaurants and cafes within a five minute walk.
Even beyond the immediate market, Palermo is a pretty small town so it's only about a ten minute walk to Teatro Massimo, the Cathedral, and many busy commercial streets with shopping and dining.
We definitely plan to return to Palermo soon and to stay at Massimo's place again!
