The pluses: great location, walkable to almost everything to see in Palermo. The host is friendly and helpful and the kitchen is pretty well stocked so you can cook for yourself. Plus the apartment is airy and beautiful.
The minuses: the shower stall is tiny and will be hard to use for larger people like me. The bed is pretty hard, almost like a futon, and so are the pillows. I would bring your own pillow if you have room in your bag. The neighborhood is loud at night (one night, I was awoken by loud helicopters, another night, loud wailing from a neighbor) so it’s not ideal for light sleepers.
I would stay here again, but bring my own pillow next time.
