8 nights in Monólithos will easily save you 8 months of therapy. Giorgos -as mentioned in other references- is possibly the nicest person in the universe, as is everybody else you might encounter at Thomas Hotel. And this expands to the rest of the village pretty much. Since we are talking mountain and not beach village, let's hope this stays like this for a few years to come.
You really should have transportation however. As a single traveller, i loved going around (to the beach but also for longer journeys) on a scooter - perfect island-life feeling!
Read the small print, have a look on the map - if you still want to go: go! I mean it: go! (the longer, the better)
