Marina's place is located in a quaint area of Santorini. Airbnb itself was exactly as pictured, was very clean and can definitely host 2 couples comfortably. Stefania's communication was probably among the best I've come across, She arranged for transportation between the port, airport and Airbnb. She greeted us upon arrival, recommended areas to visit and restaurants to eat at. She also arranged for our rental car to be dropped & picked up directly to the Airbnb! I would stay here again without hesitation.
Make sure you rent a car as the lighthouse, Fira and Oia are all driving distance.
