We (3 friends) stayed here for 2 weeks in June. This is a spacious, spottlessly clean and beautifully decorated apartment within walking distance of Palermo's main tourist attractions. The kitchen is small with a tiny work surface but the main balcony is a lot bigger than it looks in the photos.
Powerful air-conditioning in the 2 bedrooms (no air-con in the living areas), plenty of hot water and a powerful walk-in shower. Would recommend for up to 4 people but not for more than this as the bed-settee is uncomfortable with no air-conditioning and the area is too noisy to have windows open at night.
The living areas are bright and spacious, the wifi reliable and free on-street parking is available just a few minutes walk away. There is no lift but there are only 2 flights of stairs.
No supermarket or grocers in easy walking distance but Santora bar (great coffee and breakfasts in the park) and the wonderful Patisserie Cappello make up for this!
The street outside the apartment is difficult to cross, especially during Italy's 4 daily rush-hours (just step out into the constant stream of traffic and hope that all the cars will stop!) but once crossed you are 5 meters from Porta Nuova, 3 minutes walk from the Royal Palace and 5 minutes walk from the cathedral. Would highly recommend Ai Normanni Restaurant near the Royal Palace.
