Hotel Atlantis is a beautiful hotel in Thira. I chose it because it was flat to the street - no walking up lots of steps for either of us anymore! Our room was very well appointed, comfortable, and with a great shower. We had a balcony in our room that overlooked the caldera and, while others rushed to Oia to see the sun sinking into the sea, we watched the same sunset from our room. Breakfast was a delicious buffet with plenty of options for different appetites. The living areas in the hotel were lovely. It was an excellent stay!
