Very minor but your car will be parked in the village square outside the Castello (there is no space for parking inside). Its perfectly safe, Sinio is very small and secure, but I happened to have my own car with me not a rental and its a sports car and attracted attention from some local children, one of who accidentally got his bike too close and left a scratch on the car.
The location is wonderful, Sinio being a small hillside village, and the Castello having been wonderfully and tastefully renovated and refurbished by the owner. She is also a marvellous chef and she and her team create beautiful Italian food both the dinners and breakfast. And the views from the bedroom window were pretty special too. She was also extremely helpful when I had a cycling accident and ended up in casualty in Alba; arranging for a bilingual taxi driver to come to the hospital to stay with me and translate what the doctors (who spoke little English) were saying. All in all a huge thank you to Denise and her team.
