I stayed in Narella's apartment with a friend for 1 night, and it was fantastic for what we needed. Great space for 2 friends, really handy location for Palermo and for getting into the centre of Bs As, and Narella was super-speedy in responding with all the arrangements.
The shower was amazing (which was much appreciated after a few weeks of travelling around hostels!) and there were lots of facilities available had we needed them - laundry etc. I'd definitely recommend Narella's place for a couple or for 2 friends as a great base from which to explore this amazing city :)
