The Cte d'Azur is a fantastic choice, especially in June, when the weather is perfect but the peak summer crowds haven't fully arrived. Since you're considering a two-week stay and renting a house or villa, I'd recommend thinking about how much you want to explore versus relax.
If you're leaning toward charm and quiet elegance, areas like Mougins or Biot (just inland from Cannes and Antibes) offer beautiful villas, stunning views, and a more relaxed pace, plus easy access to the coast when you want it. On the other hand, if you'd like to be in the heart of things with easy transit connections, Villefranche-sur-Mer is a gem. It's got a gorgeous harbor, a walkable old town, and quick train access to Nice, Monaco, and even into Italy.
To get a feel for current rental options, local events, and lifestyle insights, this
website is a great resource. They often feature curated properties and helpful tips about living and vacationing in the region, which might give you a clearer sense of which town or village best fits your style.
Whatever you decide, the Cte d'Azur is full of hidden treasures, whether it's a quiet morning market in Menton or a sunset dinner in Antibes. Happy planning, and feel free to share more about your travel interests, there are plenty of us here who'd love to help refine your itinerary.
