Definitely the best option in Santorini, starting in the location, is near of lot of attractions and bus station, then the house is very clean and better of what you can see in pictures, this is one of my best stays with airbnb.
Aris supported us all time, since we arrived he explained us the most important information about Santorini, and also he gave us a bus schedule, the last day he allowed us to leave our luggage in his place (really useful).
He also supported arranging the transfer port - house - port
Totally recommended!!
