I was very happy with my choice of Villa Le Lanterne. The house itself is very comfortable, very well equipped and in a great location close to the beachfront (5 minutes) and to Palermo centre (about 15 minutes on the 806 bus). I didn't need to contact Marco during the holiday but I have no doubt that he would have been available had it been required.
I'd have no hesitation in recommending this as a place to stay to friends or in returning to stay in the future.
