We had 8 marvelous days at Louise’s beautiful place. The apartment was very comfortable, clean and well furnished. The view from the big terrace was just breathtaking and the large swimming pool to which we had full access allowed us to forget about going to the crowded beaches of Mondello - we would ho to town in the evenings for delicious dinners of Sicilian food. We had to climb two flights of stairs to reach our apartment - no problem for us, but might be for some. The weather was hot in August, but the aircons were sufficient for comfort - and the evenings on the terrace were very pleasant. We had a rented car - very useful to go to town, for shopping for groceries and doing excursions ( I recommend very much Sulinunte, a bit less Segesta and we skipped Agrigento - 2 1/2 hours away - we spent 5 days in Palermo before coming to Mondello and for Palermo I strongly recommend NOT to have a car). Louise was very friendly and helpful in particular with fixing a problem with the internet wi-fi, which worked very well after she provided us with a dedicated modem.
In all we had great vacations and I recommend staying at Louises strongly if you consider going to Mondello.
