We had mixed feelings about this airbnb. Santorini was beautiful and the hosts were helpful and accommodating. However, there were several issues with the room.
On the positive side, the daily breakfast was a really nice touch. They picked us up from the airport for free although did not drop us off at the ferry port for free at the end of our stay. They helped us arrange taxis and atv rental. They also gave us some good recommendations of things to do and see on the island.
Firstly, the building is not located on the caldera. Rather, it is set back from the caldera across the street. You can still see the water/sunset from the upstairs balcony, but it is not the classic view from on the caldera. Furthermore, the pictures are not from the room that we stayed in. I don't know if this is intentional, but it felt misleading. We did not feel that the quality of the room warranted the price. The room was cramped and was not very modern looking. The hot tub was not usable since the water smelled strongly like sulfur. The upstairs bathroom also had a strange smell throughout even though we never used it. We are light sleepers and were woken nightly at around 1am due to the garbage trucks picking up the trash from nearby restaurants.
Overall, our stay was fine, but if we were to come back, we would stay elsewhere.
