Our stay at Villa Diana (more accurately known as Villa Narciso/Villa Aella) was nearly perfect. The house was even better than the pictures, as was the stunningly beautiful view. Sandhy, who checked us in and cared for us, was attentive and responsive. He even offered to clean the house multiple times throughout our stay at no extra cost. The Villa is atop a massive, largely unwalkable hill, so beware - we rented ATVs to get around. The house also comfortably fits 10.
One thing to note - the location was listed for us as being directly in the heart of Ornos. It was not, however. Upon checking in, we found that the house was up a hill just above Ornos - easily accessible but beware if coordinating with others. All in all, we were thrilled and pleased with the surprising location as it was remote and the views really were unbelievably spectacular.
Thank you to Ioanna and her team - we loved our stay and would love to come back!
