I can say for sure - it's the best location on Santorini. It is right in the middle of the liveliest and the most stunning touristic area, but at the same time it's quiet and peaceful. We took a scooter and travelled all around the island and came back happy for choosing Oia and Marcos Rooms as the prior location. Great terrace for watching sunsets and doing yoga when the sun rises. Very sweet and attentive hosts. If you like simplicity - this place should be your choice.
