Replying to Ladies in Serre Chevalier!

Hi!
I'm going to Serre Chevalier january to march 2020 with my boyfriend and our friend. I was wondering if any of you got any recommendations on where to find apartments for a longterm stay. All the AirBnB hosts we've talked to doesn't rent for more than a month and we haven't found enough places so we can move to a new place every month.

And I was also wondering if any of you all are going to Serre Chevalier this winter, I'd love to have some new friends there since I will only hang out with guys otherwise. Which can be fun, but some variation is also nice during three months haha.

(Sorry if my english is bad, I'm swedish)
