Had a wonderful 3 day stay.
Avva-Mapia helped us with arranging taxi transport to and from the accommodation with no issues with nice, quick communication. Accomodation was clean, kept cool from the midday sun, good aircon and very functional kitchen (though getting ingredients to cook may be difficult - approx 30min walk from closest well-stocked supermarket) however plenty of dining in fira which is close
Great location about 20mins walk to fira and the fira bus terminal (needed for the bus to oia). Also located as a part of the 9km hike from fira to oia. Stepping outside you can see both west and east ocean sides. Great price too.
Would recommend as perfect for those who want to do more adventurous activities in Santorini.
