The island in the centre of the Seine River, the famous Notre Dame of Paris, the Church of Notre Dame, the Judiciary and the ancient prison are all on this island. On the other side of the island are the City Hall and the Louvre, and on the other side are the cultural Latin areas. Because it's very close to the referee's office and the city hall. So the security in the neighborhood is good, only some thieves. When I was in Paris, I stayed at the Latin Hotel across the island of Sidai.
