We had a lovely stay at Casa Massimo, four friends and I. The apartment was very big and felt very comfortable there despite the fact that we were a large number. The location was perfect, literally a 30 seconds walk to the Teatro Massimo, in the heart of Palermo. Claudia was very welcoming, providing us with delicious Sicilian cookies and basic stuff we needed (water, milk, etc.). I would recommend this apartment to any group of around 5 people, definitely.
