To the OP: you should consider Nice - it's both a city and a holiday resort in one, with an airport on it's doorstep. There are also 10 major construction projects underway with a view to improving the city which include a new tramway system. Nice also happens to be the place where the majority of French people aspire to live (source: Lonely Planet guide to Provence and Cote D'Azur). Average apartment prices vary greatly - in general the closer to the tourist areas and the promenade, the more you pay. To give you some idea of property prices, we have seen properties 1 street back from promenade (at the airport end) priced around 190K (new build, 33 square metres, fitted kitchen, a/c, 1 bed, includes parking)
