We have spent 6 nights at The Terrace and had a pleasant stay.
Anastasia, her husband and Popi have been very welcoming and available for any question and to give us advice and information about Santorini.
The apartment is nice and very clean (free housekeeping and change of sheets and towels every 3 days).
For those who are wondering, the jacuzzi is cold but it is really enjoyable when the weather is hot and sunny (every day while we were there !).
The kitchen is apart from the rest of the apartment and as another traveller said in his comment, it would be nice to have a little more equipment for cooking, such as a big pan, a peeler and some sharp knives.
It is located in a cute traditional village, close to every facility (supermarket, grocery store, bar, restaurants, bus stop, ATM, pharmacy, etc.).
It has free parking if you want to rent a car or an ATV (which we decided to do after waiting for the bus for hours !).
The building is in front of a meadow with goats, hens, roosters and donkeys so you might here them while you are here (especially the rooster in the middle of the night !).
I would recommend staying at The Terrace.
