We booked at Casa Ro's place for 3 nights and extended for 3 nights more - we were 2 of us working remotely and we had so much space for that. The wifi was super fast with no problems.
The location is in the center and so close to everything by foot.
The host Roberto was super nice for us, helped us with everything we needed.
I will absolutely stay at Casa Ro whenever I'll come back to Palermo!
