The accommodation itself is very unique and memorable. It's a fantastic location just a few minutes walk to the core of Oia.
It's perfect for doing the Fira to Oia hike, visiting Amoudi Bay or really anywhere else on the island as it is all very accessible with a rental car. We spent a good bit of time exploring different parts of Santorini, and it was very nice and relaxing to return to the house to enjoy the jacuzzi and rooftop for sunset. Traffic of course can get pretty crazy during the evening with everyone rushing to Oia for the sunset, so we mostly planned around that, and we enjoyed the quieter location the house provided.
There's a few minor things the unit could use (towel hangers, one upgraded mattress, more accessible path to the parking), but overall the uniqueness of the accommodation, location, pricing, and communication merit the unit receiving 5 stars.
