Great apartment with gorgeous view of the caldera. Yiannis was very attentive throughout our stay. He coordinated a transfer from the port to the apartment and all of our taxi transfers during our stay (we paid for the transfer/ cost of taxi). He also provided us with a lot of information of activities in Santorini prior to our arrival.
When we arrived at Oia, Mario met us to help us out with the luggage. Huge benefit since there are so many steps to get around the caldera! The apartment was very clean and we didn't have any problems with any of the features. (Wifi, etc) Even though you can't exactly see the sunset from the apartment... There are many restaurants close by where you can make reservations to see it.
Overall, we enjoyed our stay!
