We loved Valentina's apartment. It was very comfortable in every aspect.
There were steep stairs into the apartment but if you don't have to climb it several times a day, it is ok.
It is in an old part of Palermo and we liked the market there where we could buy fresh vegetables, fruit, cheese and meat. Or have a dinner, fresh fish done on the bbq on the street.
The neighbors can be noisy t night but that's Palermo. We had great night sleeps.
