The first and the main thing that Adriana is perfect host.
She was always in touch and helped us with all our requests. All her tips regarding places to go, to see or to eat were useful, we followed them and that why had wonderful time.
Regarding apartment. It was also perfect! Just like on the photos. It is very very clean. I think it is the most clean apartment/hotel I have ever stayed. There is everything you need while your staying. It's also easy to park a car near the building.
The city. Castellamare is good start point for travelers with car. Everything is near: Zingaro, San vito lo capo, Segesta, Trapani and even Palermo. There are several good beaches near the city, so you could choose any type you like. After the long day of sightseeing you can go to Terme segestane to relax.
So, I strongly recommend this city and this apartments to stay.
And just thanks to Adriana for our good stay!
