This was an excellent place to stay, in the historic heart of Palermo. The first view of the church clock tower as you turn into Via Orologio is stunning, especially at night. The balcony in the apartment has a great view of the upper levels of the Sant' Ignazio Church.
It is just about ten minutes walk down a semi-pedestrianised street to the Quatro Canti and is close to bus routes to visit places further afield. Nearby the Piazza around the Teatro Massimo has a great atmosphere in the evenings.
Despite the busy nature of the street below, the noise does not carry to the apartment on the fourth floor. The 85 steps to the front door would be an issue for anyone with mobility problems. But they do provide an opportunity for exercise to counteract the effects of Sicilian cucina.
The apartment is very nicely laid out and as represented in the photographs.
I would just add that although guidebooks etc. often refer to Palermo being noisy and dirty (even as they praise its merits as a place to visit) but we didn't find this at all. The central area in particular seems very well looked after, shopkeepers take a pride in keeping the pavement clean outside their premises. Perhaps not an epic city like Florence or Rome, but it has a fascinating history and there is a lot to see in a relatively small area within the historic centre.
