Very happy of our 5-days stay! The appartment was clean, with everything you need (no microwave and no tv, keep in mind if important for you) and an incredible amazing terrace with a view on Palermo's roof <3 !! It was why we chose this place and we were not disappointed!! We did not met Sofia but she answered very quickly to all of our messages so all went perfect.
The appartment is very well located in the historical center of the town, it was very comfortable. Note that there are pretty rude stairs to climb to the appartment, it's the price to get such a view on the terrace :)
I will recommend 100% !
