Hi Linda, welcome to chesterfieldonline
Work commitments and my lack of the Spanish language prevent me from being any help sadly.
I remember many many years ago as a young teenager, think I'd be about 14,
my younger sister took part in a student exchange program at Moorfield Hall (Bolsover School).
We had a french girl stay with our family for 3 week. We even went to the east coast for a week, probably Skeggy
.
It must have been very difficult for the french girl, she was about12 and didn't speak a word of english.
My sister had a much easier time in France, she was prety good at French even at that age.
All the best in finding 'homes' for the students
