We had a wonderful stay at Rosalia's house and especially on the huge, private terrace. The house was super clean, the kitchen is fully equipped and the bed was very comfy!
It is well located in Palermo: the bus stop is directly in front of the house; there are bakerys, a butcher and bars close to the house and a supermarked as well as the "catacombe dei cappuccini" are reachable by foot.
The hosts are super nice and friendly people! If you need some advice where to go for dinner, ask them! They even booked a table for us in one of their favourite restaurants :-)
We can absolutely recommend staying there - we will definitely come back there once we visit Palermo again.
