I had a wonderful stay at Giusi's place - it's comfortable and has everything you need for your stay in Palermo. It's a cool little sanctuary after pounding the hot pavement during the day (and night...it is Sicily after all!). The location is AWESOME - right in the heart of Via Maqueda - a really vibrant and fun neighbourhood, there is awesome food and drinks just a few steps out the door!
Giusi is an attentive host, and was always just a quick message away if I needed anything - she was very accommodating and made sure that I was comfortable - she checked in a couple of times during my stay and offered some great suggestions for things to do!
My only comment for future guests is to be aware that there is currently construction going on in the neighbourhood (I'm not sure how much longer for?). They worked late and started early a couple of days during my stay - so it was a touch noisy - if you're looking for quiet accommodation - it is noticeable, I found it mostly unobtrusive and certainly nothing a couple of aperitivo can't fix!
