Communication was great and they were as accomodating as possible for check in. The location was prime, interior decor was perfect for the space and age of the building, and the views could not have been any better - you look out onto the same level as the castle.
Getting luggage up all those stairs was our only "complaint" but it's an older building and it's what makes the views so great, plus we were told in advance what to expect.
Overall a great "base of operations" that enhances the beautiful history of Edinburgh. Highly recommended.
