We stayed at Casa di Bice over Christmas and New Year and it was the perfect home away from home! Paola and her family were all incredibly welcoming and friendly and were happy to answer any questions we had about the city. The apartment is beautiful and was perfect for the two weeks we spent there. The views from the balcony are amazing, you look across the city, the port and the mountains surrounding Palermo. Everything is very new, clean and comfortable. The kitchen is very well kitted out, we did a lot of cooking in the apartment (including Christmas dinner) and found everything we needed for making delicious feasts! There's a great pizzeria across the road and plenty of other places to eat and drink within walking distance.
We had a small problem with the wifi when we first arrived (it was brand new and hadn't started up properly) but Paola and her family worked hard to fix this as quickly as possible, even though it was Christmas time. We couldn't be happier with their willingness to fix a problem when it arose, and they really worked hard to make sure we were happy and felt at home.
We would strongly recommend this place to anyone looking to spend a few days (or longer) in Palermo.
