What you you say is the style of furnishing in the burrow in harry potter

I’m moving to Texas in a few months, and my fiancee and I will be renting a house. Neither one of us has very much furniture or stuff. I need some good ideas for decorating and furnishing the place without spending thousands and thousands of $$. I had a friend who would go to flea markets and refurb the stuff she found, but any ideas if I can’t find any flea market gems?

Thanks!!
