La Mer was beautiful and super convenient for staying in Oia. The experience felt authentic, which is what we were hoping for. You're staying far enough down that most of the crowds stay away and the view of the Caldera is gorgeous. (And the bed in the back room is literally like sleeping on a cloud - best night of sleep the entire trip!)
Maria was also a phenomenal host! She responded quickly to any question we posed, had a team of people ready and willing to help us out (thanks Vasilis, Ef, and the rest of the staff!), and when we got stuck on the island for 2 extra nights due to high winds and cancelled ferries she helped find places for us to stay! Maria truly went above and beyond for us!
My friend and I travel frequently and have stayed in numerous Airbnb's, and Maria and La Mer will stand out as one of our best (if not THE best) Airbnb experience either of us have ever had.
