We stayed at Guidos place for one month and we loved it. He and Maria were very welcoming and made sure we had everything we needed. Guido even sent us a mail with detailed local tips and information about Mazara.
The apartment is cozy, clean and spacious. Since most of the time we were cooking ourselves, we enjoyed the open, bright kitchen a lot. Everything you need is in short walking distance and the historical city center with its wine bars is right around the corner.
I would definitely recommend this place!
