@DanniS I love the french riviera, I went on a10 days vacation started in Rome and finished in Antibes.
As a city I fall in love with Nice, it has all the vibes you need, there is the beach, the walk, the old city, the food, nice people. It is great.
But for the beaches, my preferred place was Paloma beach in Saint-Jean-Cap-Ferrat.
Bay of Antibes Billionaires is a real hidden gem, beautiful virgin location but it is hard to swim there, but very nice to sit and read a book.
