Paying Guest

I saw a story about “paying guest” in one of my English books.
It’s someone who lives for a few days or weeks in the house of other family. This for improve a new language. It is not necessary to be a child or a student. You can be an adult person, even an old one!
I thinks this is a good way to rise your knowing of a new language and above all, talking with native people.
Do you know if that is good? Where can I try some information about that? What do you think about this?

This is also called homestay language learning.

Thank you very much keke_eo :slight_smile: I have hit “homestay language learning” in my friend ‘Google’ and found many -link- about it.
