Hi
I don't know whether you are still asking the above question but for your information I live in Stratford upon Avon UK and have been welcoming foreign students into my home for many years and while they live as family I also give one to one English Conversation lessons.
Many of my students return and all have improved their English while enjoying their two or three weeks with me and the family
Please do not hesitate to contact me if you require further information
Sarah
