The Three Terraces is a wonderful place to stay! It was beautiful, modern and the view (and sunrise) from the terraces was outstanding. Alexandros' sister gave us a warm welcome.
Use the geographic coordinates to find the house. There are few street signs in Greece. We were able to park below the house and easily walk to the village. The Kantouni taverna quickly became our "local". The food was great (better than the fancier places in Prygos) and it was a quick walk home to the Three Terraces.
Plan to get up early one day for the sunrise. It is better than the sunset at the caldera! Seriously! We spent one night in Oia and wished we were back at the Three Terraces. Oia and Fira are very crowded and Prygos is not. There are still great places to explore and all the shopping you need.
Overall, the Three Terraces was great and we would stay there again!
