Katia's place is lovely. It's a bit out of the way from the main part of Oia, so you definitely need a car or to hire a taxi to get anywhere else. Katia was very helpful in booking us a car for one day, but the taxi per day is about the same as a rental, so we recommend a car. The apartment itself is in a bit of a sparse area, but convenient enough and it's very clean and organized. Katia left us wine and treats, and she was exceptionally helpful in communication and met us to go over all the details we needed. We recommend the stay for those who want a nice view from the balcony and some quiet time away from the city centers. Thank you for everything!
