We read about the Hector Caldera Nest online from a blogger who had visited Santorini and couldn't believe everything could be as perfect as she had written. It was better! Giannis' did a great job of sending emails welcoming us before we arrived along with all sorts of information on things to do, places to swim, etc... When we arrived Dana and Dimitri were waiting for us to take our bags to the room and then Dana sat with us for a half hour going over her recommendations for the best places to eat, shop, etc... Every place she recommended was superb. Giannis arranged an amazing boat cruise for us and a car rental for a day and if we had any questions he was there to answer them. He provided a small local phone for us to use 24/7 to call him with any questions and he always responded. Given that our phones were iffy at best in Greece it was a really nice touch. I highly recommend the Nest for anyone who enjoys a great location, great service and great comfort on Santorini.
