We def had a lovely stay in the heart of Oía!
Advantages: location, quiet street, roof top (you can see the famous sunset from there without the crowds on the streets), great hospitality, good advices/tipps (walks, hikes, swim spots)
Disadvantages: no aircon, our room was a bit noisy (ground floor facing the terrace), sweet breakfast only
However, I would recommend this place if you are looking for a centrally-located but quiet spot in Oía with a good value. The roof terrace is unique!
