We stayed with Alberto in Palermo twice - at the beginning and end of our travels in Sicily. Alberto was very welcoming and had helpful suggestions on visiting Palermo! He was very flexible about arrival and departure times which was helpful. The apartment is centrally located and there are multiple rooms for rental with common bathrooms, which makes for more of a hostel environment. Everything was very clean and there was a good wifi connection. Our room was closest to the kitchen and across from the windows overlooking the courtyard, which meant there it wasn't very dark for sleeping and the sun came in early in the morning. It was also somewhat noisy if people walked through the hall.
