I did it, I was a month on the French Riviera Côte d'Azur. And I would do it again. It was an unforgettable time. I gained a lot of experiences. I met many great people with different nationalities. Nice is such an amazing city. It has very good restaurants, many shopping facilities and a beautiful, long promenade. If you visit Nice you shoud know that there is no sandy beach. The beach has just stones. If you wanna have a beach with sand you'd better go to Cannes or Antibes. Nice is a very crowded city. It is always very busy, especially in the summer holiday season. Many tourists stroll along the promenade.
If you are in Nice and you like Asian food you should go to the restaurant "Lou Colonial" (5 Place Saint-François, 06300 Nice). The staff is friendly and the food is excellent. You will not find there the normal things like rice and sweet and sour or curry rice. The food is more special, for people who wanna try something new. If you wanna eat good burges you should go the "le blast"(8 Place Charles Félix, 06000 Nice). You can eat there good burgers and many differents salads. And if you are there, do me a favour, please order a mojito. They only cost six euros and are excellent. You will become sweets and a watermelon piece with it. If you are a coffee person and you are in search of another thing than starbucks you can go to the "Café de Max" (4 Rue Paul Déroulède, 06000 Nice). You can drink there so many differents coffees and it has also good chai tea. Another great restaurant is the "Lybane" (1 Rue de la Liberté, 06000 Nice). It is a small very upscale restaurant with mediterranean and lebanese cuisine.
If you dance salsa or if you wanna try it, you must definitely go to the "Le Sansas" ( 4 Avenue des Phocéens, 06300 Nice). You can take there lessons for only eight euros. I did it with my friends and it was very funny. It has a lot people so It was a bit poky but I didn't care.
