Hi clara ,
It all depends which type of holidays you are going to have . if you are the type that w0uld want to be in nature .. light holidays with peace not too much partly it will be the west. There is flic en flac or riviere noir. Flic en flac is a bit densed. For the nice beach studio the price will be relatively high.
The north is if you want to go out at night , to a pub to a restaurant ..dancing too . it will be the north , most activity are there!
clara i would love to tell you , a nice little place, there is la cocoteraie which is not too expensive and is in the north ... i am not too sure.
please search on the internet or your travel agent. if there is some doubt. just feel free to pop in .
