Thanks Jean for dotting the i's and crossing the t's.
From our own experience: check one day ahead if a service you need is available the next day. There are many festivities in the off-season. A marriage or other party can mean a shop or restaurant suddenly will not be open.
It happened to us in December, and we will never forget that night with stale bread and just a slice of cheese for dinner, in an empty village flooded with rain, and without electricity. But we had 1 candle, and the radio was playing, on batteries: a live concert by Michalis Tzouganakis, and we knew we were far from home, and enjoying ourselves completely!
All the best,
