The staff of Ostria is very friendly. It’s a family owned hotel and the family is kind. The rooms however looked nothing like what they showed in the pictures. We requested a room with three beds (double bed and a sofa bed) and they gave us a small room with two twins. The bathroom and sink of our room were not really that clean. Breakfast was not included in our reservation. Moreover, our room did not have WiFi in it.
This hotel is good if you want to stay near the port. Though all of the fun things to do in Andros are not by the port. (It’s an hour shuttle to the other towns where a lot of activities are.)
