Nelli's place is a cute small apartment in fantastic location, just 50m from the Politeama theater. You're in the very center in just 2 min walk, which is great. It's also just 100m from the airport bus stand and 200m from the bus stand for Mondelo beach. The apartment isn't large but it's a comfortable place to stay if you want to explore Palermo.
Nelli is a very good host and she was eager to help me, whatever I needed. The place is definitely recommended for a short stay!
