Firstly, If you want to get there from Trapani airport by train (which is the cheapest option) you have to walk more less 3km to Mozia-Birgi station. Then you have to take train directed to Castelvetrano or Piraineto it cost 3€ per person. Trains are every 2 hours and you can check it on Google Maps. Then you have to walk from station Mazara del Vallo to the apartment about 800 meters. The apartment is really cool. It is well located (about 200 meters from beach and a lot of restaurants and pizzerias. It is very clean and Nicolò is very helpfull. You can use bikes which are in the apartment, this is how we traveled to more spectacular beaches like Tonarella or near Lido Kiki's. 3.5 km one way and you can get this beaches. You can also travel by train to other cities like Marsala or Trapani but you should take into account that train can be dalayed up to 1 hour or be substituted by Bus (which will drive like a train to every station). Finally, It is really nice place to stay in, very clean and well located. If you want to visit western side of Sicily you should choose this place.
