Great experience!
I was with them for two weeks.
Since I arrived they told me that I feeling relax to learn is the most important.
My daily routine was wake up, go for breakfast, two hours class, watch TV in the living room, have lunch, go to visit museums or other interested points on the city. Finally, have dinner with the family and watch The Chase. Additionally, a Sunday we went to Greenwich Park in London. All included.
I notoriously improved my English skills and made new friends.
