We had a great stay at Oia Sunset Apartments. The rooms have little living rooms and kitchenettes. And we also had a little sunset deck. Everyone who worked there was extremely pleasant and helpful, it was honestly the best service we had anywhere in Oia. It is adjacent to the town center which makes grabbing items from the supermarket or taking the bus very easy. It's also central to the shops and walkway, which can be a little noisy at night but was totally okay for us. We walked to dinner while we were there, including a walk down to Amoudi Bay. The pool was great and right next to our room. We booked our excursions in advance but they were happy to offer guidance. They also arranged our transportation from the airport and to the port at the beginning and end of our trip which was extremely convenient and pleasant. I would highly recommend!
