The apartment is exactly as pictured. We were 3 adults and there was plenty of space for us. The apartment is well-equipped with basic necessities. While the caretaker does not speak English, we had no trouble communicating with her. She and her son, who speaks good English, met us at the apartment even though our ferry arrived late. The apartment was very easy to find, and is conveniently located to Tinos town (though a car is definitely necessary in Tinos).
The only “cons” here were that the WiFi didn’t work very well in the top unit. However, on the ground floor the WiFi seemed to work normally. Also, the beds weren’t the most comfortable. But I think both of these things are to be expected on such a small island.
Overall this is a lovely apartment with a great view, and we would stay here again.
