Great apartment! everything thought of, you'll find everything you need in the apartment. the pool/hot tub is great, as this apartment is alone on the upper floor, you have full privacy there. Oia is a 10 minutes of nice easy walk from there, the view is fantastic (though not to the caldera but to the other side, but still, amazing). there's 3 great restaurants in a 2 minutes distance, a shop, a parking nearby. basically everything was ideal. definitely would recommend!
small note - there's no tv in the apartment, but i think that's for the better, you really shouldn't spend time watching tv in Santorini!
