The apartment is beautiful: it is very well equipped, and it is located two steps from the Cathedral (and very close to the vast majority of Palermo's monuments) - it is also very close to pharmacies and supermarkets.
The host is extremely kind and considerate, attentive at all times to any need that might occur during my stay - and even gave me all possible facilities when suddenly having to extend my stay.
Highly recommended accommodation: whenever I return to Palermo, I will do to stay here (because it feels like being at home).
