Paolo's place is a good place to explore Palermo for a few days. Central station and old town are easily walkable and the accommodation is as described - two guest rooms with a shared kitchen but a private bathroom per guest room. Note that you hear a bit of street noise. We had the larger of the two rooms and enjoyed using the balcony. But the best thing about our stay was Paolo's hospitality. He was very kind and fixed a leaking tap in the bathroom as soon as he could when we notified him of it.
If there are other guests staying, the wall between the two rooms is an old doorway covered in so depending on the guests, you will probably hear them.
