Great place to stay on the island. Near the bud station (15 min walk) and in the central of the island. The busses must leave and depart from Thira and this is why this location is the best! Oia is only 20-25 min on the bus and only €1.60.
In addition you will get a great host who is welcoming, gives you all the best details, and is extremely accommodating when arriving early. Highly recommend!
