Overall we were satisfied with our stay. We were greeted by the father of our host, who greeted us outside of the flat and helped me carry up our suitcase up the stairs. We thought it was quite hard to get daylight into the flat and experienced it to be much darker than in the pics. Despite it being very central, after dark the corner of our street seemed dodgy - making it kind of unpleasant to return home after a nice evening out in the great town of Palermo.
Would not advise against staying here, but would not recommend it as a first choice either.
