Rocabella Suites, 4 star
I've spent my vacation at Rocabella Suites the second winter already. It is one of the few hotels on Santorini, which is open during the winter.
The prices are not low, but I'm certain already, that a good thing can not cost low. A good service the same. During the winter, my friends are going to mountains, and I - where are not so many tourists.
