We spent 3 days at this villa in Santorini. First of all it should have been 4, but a ferry strike waylaid our plans. Regardless, Maria was helpful to adjust our dates and give us a refund even though it was at short notice.
In terms of the stay, the most outstanding things about this property is the location and the service. A porter came to help us park our cars and move the bags to the property. It isn't very easy to find but after you've done the trip once or twice, you will find yourself navigating the place like a local.
Amazing views, and the house is a typical cave house, with some extras like a wine fridge, well stocked fridge, and a great sound system. There was a nice big TV in the main room too, but who needs TV with that view!
The upstairs bedroom is very low, as is the case with cave houses, and the stairs are steep. So be careful. But overall, the house was very comfortable.
Everything that is worth seeing in Oia is nearby. And you will find yourselves the envy of the all the tourists milling about taking selfies when you are sitting on your personal porch enjoying the view 24 hours a day :)
