Antonia's apartment is in between fira main area and akrotiri/perissa. If you find it on google. You probably cant see its exact location. Search for 'Atlantica apartments' to navigate better if you are driving. Antonia was nice to provide refreshements in the fridge. The weather in santorini is really hot. She arranged airport transfer for us which was cheaper than a taxi ride. The ride was professional and comfortable. The apartment is located in a quiet neighbourhood. After a long day out in the sun, the aircon is heavenly in the apartment. Apartment is nearby a small village several restaurants nearby. We read the reviews about the frequency of the buses and tried it ourselves. Felt they were quite reasonable waiting times not more than 20mins. Usually about 1.80 to 2.40euro per trip. For a rough estimate from fira departures, maybe +10mins. Bus actually gets to several of the places for the main sites. Of course a car or personal transport is more convenient. Just be prepared for lots of curves in the roads. Do try the restaurant on the way to the bus stop. Food was great. All well cooked! Do get your groceries from Fira before coming back unless you have a car. Dont expect fast wifi though. Its intermittent but we come for the views around santorini! We were fine with it. Great stay. Highly recommend!
