Margarita's apartment is lovely - like a luxury hotel, with a sea view, complete with a welcome basket on arrival. It is about a 15 minute walk from the main part of Oia in a very pretty and quiet part of town. Margarita and her cousin, Pothiti, helped us to arrange transfers to and from the apartment, quad bike hire and gave great restaurant recommendations (Krinaki - a local traditional Greek restaurant is a must). Both Margarita and Pothiti were very friendly, helpful and responded quickly to any questions or requests we had. The wifi is also excellent. Perhaps the best signal we have had all trip.
