We strongly recommend Casa Kina! The apartment was clean and very classy, with nice and interesting little decorations and details, the location is great in the very heart of Marsala, internet and air-condition work perfectly and best of all, the host are very nice and helpful! We got lot of good tips on where to go and where to eat and whenever we had any difficulties, Gabriele come very quickly to solve them! All in all a great holiday and we will be most likely back!
Ps. The house is also kitesurfer friendly, you can dry your gear upstairs if needed.
