Our host went beyond for us. Met us at the apartment, had coffee, water and fruit. We had stopped at a grocery store knowing there was no close store. The front porch and beach right infront of us was amazing. Yes you do need a car or decide to just stay and relax. The three restaurants are all great that are 5 min walk. Can see them from your porch.
Drive up to park infront of the apartment was fun but pretty easy after the 1st time.
Tinos is windy which I was not expecting. But driving to beaches and villages our host recommended was great. There is a grocery store 20 min away but not open from 2-6. Just have to be prepared for Greek island living. The apartment is well equipped.
