Absolutely 5 stars，and actually if I can I would like to give a 6 stars.
Alda's apartment is clean, warm, quiet and comfortable, and many food will be staffed in the fridge for your breakfast. The location is just in the downtown area so that you can easily find your companions at "Piazza Duomo" which is just near by that famous fish market. Hope I can still stay in Alda's apartment if I come back to Sicilia. Thank you Alda.
