Margarita’s place matches exactly the description. You find everything you need in a perfect condition, and the whole place is very clean. The only limitation I see, is for people of 1,83 m (6ft) or taller to comfortably use the shower.
For any questions we could Margarita any time and she helped us organise a transfer from the airport to Finikia. We were welcomed by her assistant who showed us the way to apartment and also carried our luggage all the way up (~8 minutes walk). The apartment fits two people and gets cleaned daily.
Next door there are a few nice restaurants and you can also easily walk into the small town of Oia.
Many thanks to Margarita and Sefas for a very nice time in Santorini!
