My girlfriend and I stayed here for a month.
Incredible location. Incredible apartment with a little balcony looking out to the Teatro Massimo... the amazing Palermo theatre.
The food options in the area are amazing. Make sure you check out BIGA pizza. It's literally meters away, and it's amazing.
Yet the best part were the hosts.
Super friendly, helpful and very communicative.
The only issue was the Wi-Fi. Most of the time it was good, but it would occasionally drop out or be super slow.
