The most important thing is the very cultured and hospitable locals of the city, many historical temples and castles, you can walk a lot safely, unlike Paris, where you can be robbed at night by Afro-Americans or Gypsies.
Nantes is a cultural center. The art of the town is pedestrian, there a some amazing street parades all over the summer. Not to miss
A beautiful and quiet town with a decent tram system and great seafood. A visit to the market to buy fresh is a great experience.
Very Nice City, Home Sweet Home.... Nantes is a very attractive city, located at less than one hour from the coast , the economical and cultural life is very dynamic
