Amazing service and hospitality. I didn't meet Nikos in person on Santorini, but his colleague Chris (Christos) helped our group of friends get settled and gave us lots of information. Chris and Nikos were both amazingly helpful. They helped us with red eye flight transportation, gave us temporary shelter during a rain storm, and Chris was always a phone call away. Best hospitality, hands down, I've encountered in my half year around the world.
I can't recommend them enough. I would love to go again during warmer weather!
