The apartment is located right in the historic centre if Palermo. Palermo has a very large historic centre so that's perhaps not very useful but it is steps away from the "four corners" with very easy access to all the main sights of the city.
Though the area is very vibrant the flat is quiet. The bed is comfy and though simply furnished we found everything we needed for our stay.
Michi is great at keeping in touch and check in was simple.
Only warning is there are lots of stairs! Probably obvious since it's a top floor/ roof top flat but it's a climb in the heat!
Would highly recommend.
