Great place to explore Palermo, as it is very close to one of the main streets of the old town and allows perfect exploration of the old town. Some bar at the next crossing might be audible some times though.
The apartment itself is very nicely decorated and provides everything one needs. The only downside is the bed which is a bit small, and that one hears the fridge at night quite clearly such that we slept with earplugs (which we usually do in Airbnbs).
Overall, we enjoyed the place very much and found the host - respective the co-host - very friendly who also provided small amenities (water, coffee and snacks) when we moved in.
