The apartment was perfect for us (2adults and 2 children), spacious, very clean, elegant furnished, and with all the amenities necessary. It was great to have two bathrooms and we had everything we needed in the kitchen. But the most beautiful thing was the green garden & terrace, and also the landscape and views in the back of the house. Unforgettable! I also liked a lot the fact that there was silence around - the yard of the villa was large, neighbour houses were quite far.
Gregorio and Caterina were both very friendly and responsive when we needed them, and we also enjoyed their wine :-).
The only thing I would change would probably be the period of our trip - we travelled between 29th of Dec - 5th of Jan. We expected to have a warmer weather, but we had a few cold days for Palermo, with temperatures around 5 degrees C. There was a storm one night, clouds during the days, few showers and even some frozen rain...and this was not very pleasant when travelling with children. But definitely the accommodation was one of the best we had since we are renting apartments. Highly recommendable!
