The first thing to mention is certainly the very special welcome and overall care taken by Fanny, who knows Palermo like the palm of her hand and is one of the warmest people I've had the fortune to meet through Airbnb! So very grateful to the myriad ways she helped and made our stay better. The apartment itself is very well-equipped for two, kitchen/washer/AC were all great to have. I'll also mention that bugs the warmer times of year are definitely something to expect and especially on the ground floor, if that's an issue. It wasn't terribly for us.
Overall, you're in great hands and a perfect location here for exploring Palermo =)
