When you walk up from the bus stop, taxi drop off, car drop off area and go over the top - it is a sight you will never forget! You will be able to see this same amazing caldera view from the apartment and will never tire of it! Also, if you are there when it is cool, as we were at times, you are on the leeward side and so out of the wind. This is huge as Santorini is one of the windier Greek islands.
You will not have total privacy due to the Skizas Pizza employees next door, but we found them to be very polite and it really was not an issue for us. The housekeeper came everyday to clean and make the beds or change out the towels. She couldn’t have been nicer! Over all a great value in the perfect part of the island to stay in. Hardly any steps (which is another huge benefit) right on the edge of the narrow part of Oia so you have access but don’t have to fight the crowds in the narrower streets every time you want to get to your place. Hint: when you go to see the sunset - DO NOT follow the crowds to the western edge of Oia. Way, way too crowded. Instead go east to the water tower. There is a Great Wall there to sit on and have some wine and you can see the entire horizon with Oia in the foreground. No crowds (first week of Oct - which was still part of the busy season). From everyone I talked to you want to avoid July and August unless you like being packed in like sardines.
Oh, take the afternoon sailing cruise. Wonderful! Also do the 11 km hike to Fira. Can’t wait to go back!
