During the high season (July-Aug-Sept) the prices are very high, and directly on the coast you’ll almost certainly find it easier to rent an appartment rather than a house.

Due to the rocky outcrops only part of the coast has sandy beaches—those between Saint Raphael and Juan-Les-Pins (west of Nice), and also around Menton (east of Nice). For the most part there’s a main road between the housing and the beach, however it’s not unduly dangerous (in fact in the high season traffic is likely to be crawling).

Restaurants are mainly concentrated around the actual towns and villages, so for example although La Bocca has easy access to the beaches you might find walking into Cannes for the good eats a bit of a drag. If on the other hand you mean easy access by car you’re spoiled for choice (with exception to the above note on traffic—there’s always the train).

Best option is to find some rentals you like and then look up their locations on Google Earth/satellite maps. There’s little along the coast not to like (except perhaps the flat bit between Antibes and Nice).

WayZ, the problem is:
What do you want to see/ live by?

Are you interested in the rural, scenic cote?

Or the flashy,shiny part?
Answer depends, as so often.

Actually, using google maps is way of cool for choosing.

Anyway, since my predecessor and I assumely know the cote like the inside of my wallet, we might ( at least ) have some advanced tips for you !
