Yes went last September lovely place. We stayed in the middle as we hired a private Vila with pool and wanted to hire a car/quad to explore the island.
Oia def needs a visit as its what is used in all the pictures and it's just as beautiful in real life. Word of warning gets absolutely packed at sunset time so much so you can hardly move through the narrow streets.
Fira is fun to walk around and do some shopping.
Perissa beach was prob the nicest.kamari has bars & restaurants along the front and we preferred it at night as a change to Oia/Fira.
