Torino definitely has a warmth to it as a place to live in despite the freezing cold.

It'll in fact be perfect for family life. As for the club, I don't personally rate Juve as a 'warm' club but most clubs dont fit that category because football has today become a business.
However, Conte's presence makes a big difference. He is an astute coach, both physically and just as importantly, psychologically. He gains his respect despite a relative lack of experience because he works more in the capacity of a mentor than a manager. It's so evident that you can see it in every player that has played for him this season. We were not even in the top two most talented teams in the league, and yet we won it because of one simple reason: teamwork. He made everybody play for each other. It is because he instilled a strong sense of belonging to everybody on the team, and will do the same for Van Persie to make him feel at home. For me, a winning environment creates a warmth and camaraderie of its own. A coach like Conte is according to me, the kind of person somebody like Van Persie would thrive under even if the other conditions you listed historically may or may not work against him.
