We are very very satisfied with Gaia's place! The location is just perfect, next to the Normans palace and Palermo Cathedral! There are acctualy few appartments with common closed courtyard, which is very nice, quiet and safe.
Our appartment was Ulivo, which is stylish app with bed on the gallery on top. Everything is new and clean, especially bathroom. The host, Gaia and her staff are very helpful and respond quickly, and we are thankful for the late check in that was possible and simple. Gaia will also recommand you where to find parking, which is a bit tricky, but we managed to find a place in front of her appartment :)
All in all, great stay, we recommend it and would come back!
