We stayed in the apartment for 4 weeks. We're going to start with some of the cons: (1) the place looks much nicer in the pictures. We didn't mind this too much, but the place was a little smaller than we expected and there were a lot of aesthetic issues such as bathroom rust, mildew, stains on the walls, etc. The place needs some touch ups (2) There was no operational washer or dryer, as advertised, so if you need to do laundry you'll need to walk a couple blocks, which we were OK with (3) it's quite noisy; Palermo Soho is a lively place so you'll likely here people partying it up sometimes all night until 7AM mostly on the weekend but occasionally on weekdays as well; there's also constant construction all over Palermo. We got good sleep any way but if you're a light sleep if might bother you
The pros: (1) the location is excellent. We had access to AMAZING variety of cafes, restaurants, shops, bars, bakeries, markets, amazing gelato, etc. It's food and drink heaven. It's also got really fun night life just blocks away. And it is a very safe area (2) the staff are wonderful. They were sweet and helpful and respond very quickly on WhatsApp. There is always someone downstairs at the desk 24 hours a day. They helped us with everything including airport transfers. If your Spanish isn't good it's better to just communicate with them through WhatsApp, they respond very quickly (3) The apartment itself was cleaned consistently and we were given fresh linens, towels, etc. (4) We were worried that WIFI might not work because of one of the reviews on here but it worked just fine
