We visited Santorini for a family vacation combined with our babymoon. We had a great time at the Oia sunset villas. The property is exactly as it is listed and perhaps provides the best unobstructed sunset views. Marcos and his staff were very responsive and helpful all throughout our booking and stay.
The only thing I would call out to consider - it is about 10 mins walk from the main Oia pedestrian street, so may not be ideal if you are looking to stay closer to the restaurants (as the property doesn't have any food/snack options) and enjoy the Santorini views with all white pristine properties by the Caldera. If you are looking for a relaxed vacation away from all the hustle bustle it is a great place and location.
