Me and my friends had an amazing stay at Casa Raffo Rosso! It's a spacious recentry renovated apartment, with two nice bedrooms (1 double and 1 twin), living room, large kitchen, large terrace with great view of the city and of the Mount Pellegrino.
WiFi works well and there is air conditioner in all rooms. The flat is quite near the center (approx 15 mins walking) and just 5 mins walking to Palermo Notarbartolo train station where are trains to/from the airport. The flat was furnished with all kitchen appliances and the basic ingredients for cooking and having breakfast and there is a supermarket just in front of the building.
Giusy was out of town but her friend managed the check-in and check-out very professionally.
Absolutely reccommended, Casa Raffo Rosso met all our expectations and we couldn't really have hoped for a better place in Palermo!
