We had 4 great days in Santorini thanks to Anna & Maria. The pension is 20 minutes from Fira by walk, which was really convenient. You can also rent a scooter, quad or car at the pension and buy tickets for the volcano excursion, which was perfect for us ! The pension offers the transfer at your arrival and you'll also enjoy the nice pool !
It is also possible to travel by bus on the island, there are bus stops 5mn from the pension or in Fira.
Don't hesitate !
