We had a great stay in Leonardos home. The apartment is very stylish and really big with a well equipped kitchen. Also WiFi internet access works well and is fast.
We only stayed one night - I'm not sure if it's always like this in Palermo. There were fireworks in the middle of the night and a noisy neighbourhood (not in the house, only outside).
If you want a central place in Palermo where you can reach the POI within walking distance then this is the right place for you!
