I stayed 2 month. Small but complete apartment. Quiet and safe area. Super walkable to Palermo and close buy sights. Definitely recommend staying here if you visit the city for a short period. For me it was perfect but can imagine other people prefer more space when staying for longer.
Communication was great, host left some power converters and a Subway card with some credit. Internet speed was incredible good so working from there was no problem. Two subway lines are in proximity and all the hip places of Palermo are within 10min walk. Only downside of the apartment was that the laundry is not in the apartment --> communal laundry at top floor (free). Kitchen has everything you need to prep small dishes.
Thanks again for letting me stay at your apartment!
