We had a fantastic time and loved our stay! This location has some of the best vantage points in Oia - with both sunrise and sunset views from the patio. Our host was very responsive, was able to make arrangements for us on very short notice and set up most of our activities during our stay in Santorini. We'd HIGHLY recommend the catamaran day trip - it was absolutely amazing! Additionally, we were offered transfers to and from the airport. This worked best for us and I would urge most travelers to go this route. Oia was roughly 25 minutes from the airport and streets aren't the easiest to navigate.
We'd definitely refer Thireon Houses as a place to stay while visiting Santorini!
