Auntie's Villas is a gorgeous place, located in a very traditional village (where you can find everything you need) very closed to the most well known area of Fira, Imerovigli and Oia.
Definitely recommend to rent an ATV or even better a car to reach the house (there's a downhill to reach it).
Very private, very romantic and very beautiful view from hot tub in the terrace (in the early morning you can enjoy a fantastic sunrise).

Marios is a great host, really recommended
