Maria apartment is very nice. Starting from location till small details. It was very easy to communicate with her and she answer for all our questions. Apartment is located just in few steps from main square and famous fountain. Very good equipped, we stayed there for one month and it was very comfortable for us :)
Also it is very clean, and host provide us with some water and fruits to our arrival. :)
If you want to visit Palermo, I can recommend Maria apartment!
Thanks!!
