A good place to stay in Santorini, 15 minutes away from Thira and a bus station is 100 m away. the place is beautiful and the pool is nice, especially after a day visiting in the sun. The hosts will always answer if you have any questions and it helped us a lot.
However, the apartment is not really handy because there isn't everything necessary in the kitchen and the shower is really small with a curtain quite unhelpful.
