Hi, no problem for your english, i'm french so...
Size and furnitures of cottage and Junior suite are almost same.
The bigest difference, is that junior suite have a direct view on the sea, nothing except sand of cliff between the room and the water. Also some others details, like in front sea view, you have a cattle and tea pot...
Cottage are second and part of the third line but very spacius and confortable.
Regards
Myriam
