Overall, this is an immensely worthwhile place to stay. The room is fairly spacious, the bathroom nice, and the rooftop pool, gym and relax spaces are really nice.
The location is just about perfect. An easy walk to the parks and botanic gardens as well as to Palermo, but also plenty of little restaurants nearby with a more local feel than what you find in Palermo.
The “kitchen” is not much. A two-top electric burner. Sufficient for making breakfast but would be difficult to make a full meal. Also, there isn’t really a suitable knife for prep (which is an easy fix).
The windows don’t open but you can open the door out to the patio for some air circulation.
This all being said, I did have a bit of a frustrating experience trying to get responses from Fernanda prior to check in, as others have mentioned, and we were told we’d have to check in later than the check in time.
The place is great and the location is solid, just be alert these are potential issues that may crop up.
