The apartment is part of the beautiful villa situated on the mountain slope in the olive garden (however accessible only by car). It is a part of the house of Maria Chiara's parents but the ground floor where you live has separate entrance and wonderful garden - it is really calm and peaceful. The apartment is fully furnished - there were two of us and it was more than enough for a comfortable stay.
The cottage is perfectly located if you want to explore the north-western part of the island (and it is totally worth it). Between Trapani and Palermo, it is within 15-45 minutes to all the local landmarks (only to mention Riserva Naturale dello Zingaro, Monte Cofano, Erice or Segesta). Castellammare al Golfo - the nearby seaside town provides you with nice restaurants by the marina and winding streets of typical "Meditterraean" town.
Last but not least, Lilia and her husband are wonderful hosts. They were helpful but on the other hand respected our privacy. They treated us with the best figs and orange jam we've ever had. It was a pleasure to meet them and stay at their house.
I sincerely recommend staying and Maria Chiara's apartment!
