Well first of all we did have a nice time in the apartment.
But I have to make a pros and cons list:
Pros: beautiful neighborhood, with a lot of cafees and restaurants.
Martin was quickly to reply.
The balcony and the pool area is very nice.
Cons: We had a bit of misunderstanding about the check in.
The water heather didn't work, but was fixed the next day.
The kitchen wasn't really equipped for making food, which we pointed out at which also was "fixed" to some degree.
The apartment generally seems a bit torn down.
As other have pointed out, the apartment wasn't cleaned very well. The closet doors doesn't work, the curtains works on and off and the airconditioner is extremely noisy and unreliable.
The drain in the toilet must have been broken since there was a constant smell from it.
The apartment actually isn't situated in Palermo, but at the outskirts of it.
Besides that we had a nice stay.
