It looks great in pictures and location is excellent, but the place is full of problems and hasn't been maintained well over time. I stayed there one month. I stayed in several AirBnB's around Palermo for the six months I lived in BA, and didn't have issues with the others. The apartment hadn't been cleaned thoroughly - so dirty under the chairs at the dining table and in corners.
Lack of privacy/security: one day the access key just stopped working and owner told me where to find a spare one. He then left a new one on my kitchen table - he entered my apt without first asking for permission, especially when he could have just slid it under the door.
The hot water in the shower upstairs doesn't work reliably. You have to play around with the gas burner downstairs first in order to get the hot water upstairs to work. They tried to fix it, but never worked reliably. And then, the water is either too hot or too cold. And after they fixed this one day, I came home to a flooded apt. The water stained my new Tango dancing shoes and ruined them. I had bought some kitchen towels, which got stained when his staff used them to clean the flood water from the floors.
One evening, I'm ready to go Tango dancing, and the hot water just didn't turn on - I spent 15-20 minutes trying to get it to work. I ended up having to take a cold shower - on a very cold night in May. The owner didn't respond until the next day.
Things that have not been maintained: only one AirCon remote for both upstairs and downstairs units - they can't bother buying a second one. The garbage can is broken, and the owner told me he would replace it, but never did. The kitchen doesn't have complete set of bowls/utensils - looks like they haven't replaced things over the years. The cushions on the couch are mis-matched. The place lacked a lot of simple things - like matches to light the stove, or enough cloth mats for the bathroom (I bought some) to keep feet warm on the cold tile.
It's one of the more expensive units in BA, and yet they bought the cheapest toilet paper possible. I had to replace it. Then you realize that the downstairs toilet paper holder is a cheap one and doesn't have space for a full roll.
I just had higher expectations for such an expensive place. They're in the mode to extract as much money from the unit at this point...
