Definitely above any expectations!
I think that if you want to live a unique experience in the city of Palermo, having the possibility to stay in one apartment like the one made available by Marcello, is an added opportunity!
The apartment is large and spacious, and inside it has everything you need and even more... It is perfectly clean, as well as neat and well-kept. In addition, it is located in a strategic point of the city, where a few meters away you can walk to the ancient food market called (Capo) as well as being very close to the Palermo's Cathedral and the other major monumental artistic attractions. The host, Marcello, is available 24 hours a day, just in case you have any need or questions (but I doubt if there is any need for support regarding the apartment: it's perfect as it is) Apart from that, Marcello will be happy to explain and show you the area where the apartment is located, giving you some useful tips for practical stuff around there.
Flexibility also for the time of check-in / out
I will recommend this apartment to my friends and work colleagues as well, as definitely going back myself when there is an opportunity!
5 stars ;)
