I recently visited Prato for the second time. It is amazingly beautiful and off the tourist track for anyone who wants to really get a local experience whilst travelling.
I want to give a high commendation to a very lovely lady, Simona Cozzi who i host at the delightful B&B we stayed at. Her B&B, Ma. Gi. Co., has been handed down through generations of the family and Simona still lovingly runs this business, faithful to family tradition. The cost was Euro 65 per night for two, including a generous sized room and a magnificent breakfast, cooked by Simona. The B&B is close to a railway station, Prato Porta al Serraglio and provides a home away from home, whilst experiencing the best of local Italian culture and cuisine.
i can't recommend this place highly enough!
