Ann was more than helpful and responsive in communicating with us and very flexible about our uncertain arrival time. We had a few questions during our three-night stay and she was always fast in responding. We doubt you'd find a better location in terms of value and proximity to the best of Edinburgh. The view of the castle was stunning. The apartment is within a quick walk of the Grassmarket area and Royal Mile, yet very quiet and private. We didn't need our car the entire stay. Highly recommended.
