This is the nicest Airbnb experience I have had. The apartment itself is even better than pictured. It is spacious and has everything you could imagine needing, including beach towels and some adorable furniture for the patio. Antonia was wonderfully thoughtful and attentive. I arrived late from a flight and Antonia was kind enough to call me at nearly midnight to give me tips about the apartment upon arrival. She was helpful in sorting out rentals for a quad nearby (Diamantis Rentals for a fun, unique way to get around the island), helped sort out lost luggage from the airport, and booked taxis for the airport arrival and drop-off. Truly above and beyond.
Megalachori itself is charming and lovely. The staff at nearby Petrino were incredible - I went back three times and enjoyed the wonderful company and views from the outdoor seating area. Highly recommend walking to Pyrgos for the sunset. Book this place straight away and enjoy your visit to Santorini! I hope to be back again one day.
