We stayed one week at Francesco's place and we had a really good time in Mondello. The apartment is well located, the beach and the center of the cute village of Mondello are about 20 minutes walking, the nature reserve of Capo Gallo about 25/30 walking. The place is cute and quiet, just get some mosquito repellant for those who have sensitive skin!
As for Francesco, he's a good host, gentle and friendly, and his family too. Thank you again for the pesce fritto and the Spumante :-)
By the way, we also rent bicycles and it's the better way to discover the village. We really enjoyed our stay!
