The apartment is clean, very minimalistic (feels like a rental, not a place people actually live), but has everything you need or a stay. It has a nice pool view (balcony to the back of the building), it's pretty quiet for a capital, no street noise at all (but you can hear the neighbors sometimes, not too annoying and silent at most of the night times).
The balcony has a nice pool view (we missed some furniture, but it should be replaced soon). The bed is very comfy and the internet speed is good. The kitchen is equipped for cooking, there were some spices, coffee, and tea ready, also cleaning stuff is provided. The bathroom is fully functioning with good water pressure and hot water. The location is okay, it's a little away from Palermo center, but still close to a lot of things, small supermarkets & bakery is around the corner. There is security 24h and it's very safe. The laundry is shared and it tokens you only can get from Mo-Fr from security, it was also busy every time we tried to wash - so better do it during day times and plan a little ahead, especially if you need the dryer. The pool is a big plus at this apartment, it is big enough to do some real swimming and very clean, with nice lounge chairs (midday to late afternoon sun). The balcony gets a lot of sun from late midday till the evening, so very nice to sit out there.
Overall, we would recommend, but a little unpersonal and not necessary information available when you check-in (check-in is with security, you need to provide passports and then the apartment has a code lock).
