Our host was great. We had no problems. It was an 8-minute walk to the main square at Mondello Beach, with stores, restaurants, street-vendors, and groceries. The on-site, gated parking was very nice.
Driving in Mondello and Palermo was thrilling, a bit like Mad Max Fury Road. Rules, signs, and lane markers are irrelevant.
It was unusually hot during our stay, but the villa has air-conditioning in the bedrooms and kitchen, so it was all pleasant. I wish we could've enjoyed the terrace more.
