Hello , I'm 16 years old , I'm French and I foresee coming to Greece in June/ July 2012 for one month. I am looking for a serious host family to welcome me in the capital. I'm very serious !! I can do baby-sitting because I used to children and babies for many years. I often keep children here in France. I can also help you learn French I speak French, Spanish and a little English at least I can make myself understood . Bye !
The Easy Expat guide to Athens would be a useful resource for you. It has info on visiting/living in Greece. You may also try contacting people directly through the network. Best of luck & let us know what kind of resources you use.
