Is it possible to have a rental of one month around February, we are a retired couple and we want for the first time to experience leaving Quebec in winter. Thank you in advance for answering me.

It's near impossible to rent one with short notice. Also 3 months rental is standard. You wou have to look now for next winter. Dale

I wish I spoke French. So I will say this; call a realtor & have them call to get you a rental,or do your research on line and find a realtor at Jensen Beach to find what you might want for the approximate time you want and then do more research when you get down there for the following year. God bless and good luck.
