First of all the place was really beautiful. And if you want the perfect view, stay here!
Service was superb. Louana, and all her staff were warm and very welcoming. We were also provided with a mobile phone for easy communication and Louana responded pretty swiftly.
As we were here during the non peak period (late February), there were constructions beside us (the work ends early evening so it didn't bother us), and the power got cut for a short while. But overall it didn't affect our Santorini experience:) So if you are looking to stay here during non peak period, this is something to take note of.
