The final leg of our journey took us to the Cote d'Azur region, where we stopped off in Nice. And I LOVED Nice!!! The beach was SO clean (the city made a daily effort to keep the water clean) and beautiful, although it was a stone beach. Only thing that would've made it nicer is if it were sand.
Final thoughts: Cote d'Azur AMAZING and I want to see more of it. Monaco, mixed feelings. Go if you like Formula 1 or gambling/money-extravagance. If you aren't keen on those, skip it.
