We are a couple with two children and we usually have visitors in the summer and help them with their Spanish.
We live in Arenas de San Pedro, a very nice mountain village, at 150 km. from Madrid. (http://www.aytoarenas.es) We live in a flat in the centre of the village. As Arenas de San Pedro is a holiday place for Spanish people (most of them from Madrid) there are many things going on in the summer. You can enjoy the natural swimming pools, sitting on a terrace, horse riding, etc.
The prices are the following:
600â‚¬ per week. This will include full board (breakfast, lunch and dinner) and picking/taking you to the airport.
If you are interested please contact us and we can answer all your questions.
