Luisa is a great host and her place is small but nice, good for a couple of nights while visiting Palermo. It's just minutes away from the best attractions and restaurants!
Only problem we had was that we came during some hot August night and, being the place a bit difficult to aerate (plus being in a central location it can be smelly/noisy outside), we had to keep the A/C on during the night; however that proved a really noisy machine - I had to use earplugs to sleep.
