David's representative met us at the flat when we arrived, and did a great job introducing us to the flat and the local area. (The flat is several flights up with no elevator.) He left two sets of keys, including a quaint old-fashioned key for the flat itself. The location is good, directly next to the Edinburgh castle and looking out on it and its constant activity. The water pressure was iffy, especially for showers, but we learned to deal with it. The windows are small, and the views are actually better walking around outside. We had a great time.
