First the good, and it is mostly good.
The people at Wonderful Italy are very kind and helpful.
The location is fantastic, right in the heart of old Palermo, easy walking distance from the train station, the waterfront, and many interesting sights and good restaurants.
The apartment is beautiful! I fell in love with the roof terraces, not thinking about the fact that having the roof means being on the top floor. That would have been no problem if the elevator had been in service at the time.
The other issue that was not in Wonderful Italy's control was that the boiler had gone out, meaning no hot water.
If these problems were fixed, this rental would be pretty flawless.
I would stay on a future trip.
