What a fantastic building! The location is undoubtedly one of the best in Edinburgh. We loved people watching the castle visitors. The apartment isn't double glazed and full of contemporary features but is an old character building, furnished accordingly and it is comfortable and clean. An open fire would have been fantastic but no one in their right mind would carry fuel up those stairs. I felt for the servants back in the day. We felt very privileged to stay in such a lovely place.
