The appartement is very pretty, clean and nicely decorated. The kitchen works perfectly and the small balcony is fantastic with an awesome view over a nice square, huge trees and the sea!
Surroundings: the historic center is very pretty. Everthing like supermarkets, small shops, cafes, ice cream parlors, etc. are very close.
But you should notice that for excursions and the transport from/to the airport you should definitely rent a car. Theoretically it is possible to reach the tourist attractions and the airport with public transportation but it is not easy!
Also you should know that most people in Mazara only speak italian. So you should definitely bring a phrase book if you, like me, don't speak italian ;).
