Nikolas and his listing were great! He was friendly and approachable from the start and quick to respond. The apartment if fantastic and the position is amazing - other reviewers have mentioned the privacy of the terrace and outdoor pool and that is quite accurate: most other balconies in Imerovigli (and Santorini!) are overlooked by other accommodation or walkways - this one feels very tucked away but you still have a spectacular view.
The maid service was nice and everything is an easy walking distance from the apartment - fantastic restaurants, market etc.
I would definitely recommend this apartment for a Santorini stay if you would like some privacy and great views but still easy access to the hustle of the larger resort-style towns.
