Fantastic location, good sized apartment, lovely views from a private outdoor area (although the balcony is shared with two other apartments, it is large enough to make you feel like you have your own space). Excellent local tips and suggestions from Andromahi, and she was incredibly helpful with transfers, etc. A truly iconic Santorini experience.
[It is important to know that there is no air conditioning (which is really only an issue when it is really hot - there are plenty of fans); and the sleeping areas are not suitable if you are have any issues with climbing ladders - mind you, if you have any issues with climbing, most locations in Oia are going to be problematic due to the number of stairs you will need to climb on a daily basis.]
