We're a family (adults, teens) planning to visit the Cote d'Azur for about a week in July. We're looking for recommendations about whether to make our home base in Antibes or Villefranche-sur-Mer. Both look charming; we thought there might be more to see in Antibes, its cultural history interests us, and the write-ups of the old town make it sound appealing indeed. But we wondered whether the old town is lost in the hustle of a more modern surrounding city? Villefranche seems charming too but we wondered whether the sights and activities there are more limited (or not!). We do expect to take the train from either town on excursions to Nice, Monaco, etc. We would love advice from folks who know these towns -- thanks so much!
