Negative points : None !!!
The flat is perfect with all required equipments.
You need help, Elena is very kind and pleased to help you. By the way, around if you need something and you say you stay at Elena's place, people are more than welcome to help you.
You want a bike for a tour, just ask to the neighboor :)
Incredible accommodation close to the historical centre. I will not wait again 16 years before coming back to Palermo but now I know where I'll will stay again. Highly to recommend !
