The location of the apartment is perfect, as it's located in the old town, between the important roads Maqueda and Via Roma. Also the train station is quite close. Although it's central the place is rather quiet and we had a good night's sleep. The interior is nice, clean and rather simple and in the kitchen we found everything we needed for cooking. There is w-lan, the connection is not very strong but alright in the upper floor. Be prepared that there is not a lot of sunlight in the apartment, but I guess thats a plus in summer. Also the city of Palermo is so beautiful, that you shouldn't spend your days inside :)
The service and communication was good. We really appreciated, that the sheets and towels were changed after one week stay.
All in all we enjoyed our stay here and considering the great location the price was really alright.
