We were a family of 7 traveling together. We stayed in two of the houses. Helios had an amazing view of the sunset from its rooftop terrace. It also seemed to have the most photographed blue door in Oia. Our other house had a nice hot tub. Maria was beyond helpful: booking our transfers, having her guys move our luggage, bringing us wine and ice cream cake on the terrace. This was a stay of a lifetime!
