We enjoyed 6 nights at Lucia's apartment centrally located in the lively "centro" portion of Trapani! Bars and restaurants were just steps away as was a small supermarket. We also enjoyed walking to the nearby beach .
We had a rental car which we used to explore the countryside (as well as to drive to the Erice cable car entrance). Lucia suggested we park for free in the town center parking lot across from the beach about 1km away and that worked out very well!
Lucia was an outstanding host! There was a small issue with the air conditioner and she addressed it right away, and when I asked to borrow a couple of wine glasses she happily lent them to us!
We had a great stay in Trapani and highly recommend you visit as part of your trip to Sicily!
