We really enjoyed staying at Germana's place. It was clean and tidy with the photos doing it great justice. As for the location, it was 5 minutes walk to Cattedrale di Palermo and very close to the Capo market. Teattro Massimo, the main shopping street and transport via the train station or to the airport was all within a comfortable walking distance (15-25 mins). Would totally recommend this as a base for your Palermo trip!
