Maria's place is an amazing location overlooking the classical pictured domes. There is a line of tourists outside of the place. Oia is a very touristic town with thousands on new tourists everyday so be prepared for it. What they desire is the view you have. The cave house was clean (cleaning service daily). It was large for us (3 persons). She had A team is persons coordinating arrival, check in and checkout. Very professional.
Would stay again if visit oia.
