German student for classes and fun with kids

HI,

We are a family of 4 living in a small village near Oviedo. We are looking for a german student to stay with us 15 days in July (1-15). We are flexible. You can stay living with us or, you can come everyday for few hours. The idea is to expend some time with the kids to practice german and have some fun with them. 

I don´t know what to offer as a salary as it realy depends on the deal.

talk to you soon

Noelia
