Via Volturno is amazingly central to Palermo! Not just the opera house (two minutes away) and the spectacular Capo market (two minutes in the other direction) and Via Maqueda's new pedestrian zone, Antonio's apartment is ten minutes walk from the bus to the airport, fifteen minutes to the Palermo hammam and practically next door to the delightful Rabbit Hole, a tea house on an Alice in Wonderland theme. Quite nearby are the cathedral, the archaeological museum and buses to everything else.
Finding Wi-Fi was a problem for me, however.
I cannot imagine a host more determined than Antonio to solve my particular problems with the noise of the busy street. His courtesy and consideration were most impressive.
