A video review of Grace Hotel in Santorini – The best hotel in Greece. Other great hotels include Katikies (Oia), Canaves (Oia), Perivolos (Oia), Astra Suites (Imerovigli), The Belvedere (Firostefani), and Aria Suites (Fira). Santorini has the best luxury hotels in the Greek Islands. Mykonos also has some wonderful boutique and luxury hotels but they do not get the incredible caldera and volcano views like the hotels on Santorini. Grace also has the largest infinity pool along the Santorini caldera.
