The appartment is extremely beautiful and right in the city center. It is very spacious and clean, we had a great stay there. The only thing is that it is located in a busy street, there are a lot of bars and in the evening there is quite a bit of noise. The windows are very good so we had no big problem but if you are a light sleeper maybe it is not for you ;)
Francesco was great at all times, always responding. All in all we had a great time in Palermo!
