Bus stop is within few minutes walk from the villa. Bus services are running throughout the day towards the central bust station. From there connections are available enabling visiting other areas of the island too. However a car is recommend as this would allow guests to visit different areas of Santorini quicker, easier and take your own time. Renting Scooters and Quad-bikes may also be a good idea and a nice experience. If you are familiar with those it may worth trying.
