Let me start with saying that Chiara and Federico are great hosts. They went the extra mile to make our stay pleasant. The apartment is fully equipped and has everything one needs to get started in Palermo (even the first breakfast, boardgames and any household product you can imagine). The kitchen is also well equipped.
We stayed at the apartment for 7+ days while mostly working. The area surrounding it is pleasant during the day and evening with good restaurants, cafes and leafy streets. There are even 2 parks nearby for little walks. It is a bit of distance to the old town but we actually enjoyed the 20 mins walk at night and there is also always the option to take an electric scooter (if you dare) or the bus.
The one thing to be aware of is that the bedroom is facing a noisy street and the windows are old so you will hear a lot of road noise throughout the night. earplugs are highly recommended.
