I spent a whole week on my own at Daniele's place in Palermo. It's a spacious house (a corner of a palazzo, so to say) in the very heart of the city. The main disadvantage is that the street is very noisy at night (every single day of the week!), being crowded with eateries that are extremely popular among locals -- but for me this was not a big problem. Daniele responded very promptly to my messages, and the place was exactly as described. I appreciated that I was allowed a late check-out. I'd recommend this place even to a larger group of people.
