This is my fourth Airbnb in BA (Palermo). Overall, a very cozy apartment with everything you could possibly need. The hosts were great, check-in was easy, and the interior of the apartment is beautifully put together. It has a really nice aesthetic & quality appliances.
It's a little on the small side, which didn't bother me at all, but if you're looking for floor space, this may not be the best pick. Additionally, the apartment is on Santa Fe - one of the busiest streets in Palermo & not the most pleasant late at night. This isn't a major issue (and the apartment doesn't have any noise issues), but it's not the best street to live on. Also, the wifi was the most unreliable of the four places I stayed in.
Regardless, this is a really great spot to stay in Palermo and I'd happily return.
