NICE
This pretty city is the 5th town of France, it is also the prefecture of the Alps Maritimes. Therefore I grant as much importance to it.

Moreover it has certain nonnegotiable advantages such as the Italian border has a few kilometers of (30km approximately), which makes a great tourist city of it.
It is a very active city with more than 933.080 inhabitants, with many entertainments close being largest of France: two Palates of congers, the second airport of France, large districts of businesses, many luxurious hotels, an Opera, a Museum of Contemporary art and a media library.
With all these things, impossible to be bored at Nice !!
