This spot is THE spot on Santorini. Walking down to the rooms you will run into tons of people taking glamour shots of the scenic view you get to enjoy privately from the patio. The apartment was clean and cool, romantic, and very centrally located near tons of restaurants and shops (and you get quite a workout from the stairs - up to you if this is a pro or a con!).
The recommendations given to us by Catherine were spectacular, however we didn't have enough time to do them all.
When leaving, we were a bit taken aback by how much the cab ride was to the ferry (it sounded like it was being arranged as complimentary travel to the port, as other Airbnbs in Greece happily do). If you're on a budget, make sure to check the bus schedule as you can get to the same places for less than 2 Euro (compared to a 30 Euro cab ride).
Overall we had an magnificent stay and were extremely happy with the airbnb. Thanks Fanis and Tina!
