Nino's place is amazing!
As soon as I entered it, I felt entirely at home, you can feel that every single detail (and there are many artsy/aesthetic details) has been carefully chosen and brings up different emotions. It has the beautiful simplicity and colourfulness that only a heart-warming place can have.
This is, of course, a reflection of the owner's personalities. They are extremely friendly and kind and made everything very smooth during my stay, also giving hints about places to visit and what to eat at the beautiful city of Palermo and surroundings (Giuliano - Maria's son - and Maria were very kind and helpful during my stay, promptly replying to my messages and giving nice advices).
On the technical aspect, the location is very central and very safe, close to the Capo market and its many regional (and tasty) products. The place is super clean and well decorated, with very good WiFi, a shared living room full of books, a shared kitchen with everything you need (even food for your breakfast) and, the cherry on top, a terrace with an amazing view of Palermo where you can have your meals or just chill during the sunset.
The room was also very comfortable and had an air conditioning system for the hot days. The private bathroom was very close to my room, which was also good.
Final verdict: If you want not only to stay in Palermo but also to have a comfortable and heart-warming experience, do not hesitate to stay at Nino's place :)
