Santorini is a as expensive as it gets. Most rooms in the super scenic part of Oia go for $500+ in the main season. It is basically one small cliff but with incredible views.
Now Alexander’s Boutique Hotel of Oia has filed really affordable off-season rates of $82 for most of November 2015. It’s much lower than most of the rest of Oia hotels at the same time.
I’m myself headed for the Greek isles this summer – though I wont’ be stopping in Santorini this time.
